While browsing through the internet in our daily life, one of the most commonly experienced and encountered error over the internet is the HTTP 400 bad request. There may be various situations during the daily use of the internet by you, in which you would have encountered this error. This article gives you an overview about HTTP 400 bad request error, what it is and why is it displayed.

The cycle of a web browsing activity or a web search involves the client computer and the web browser used by at the client side, as well as the web server, where all the resources such as the web pages, images, videos etc accessible over the internet are kept. The client machine requests information from the web server, based on the protocols set by the HTTP, that is the hypertext transfer protocol, and the web server displays the desired files, which can be accessed on the client side using a suitable web browser.

What is HTTP Status 400 Bad Request ?

A HTTP 400 bad request occurs whenever the web server terminates this search cycle and does not allow the client to get access to any particular information requested, owing to a particular reason. In the simplest terms, a HTTP400 bad request occurs when the web server turns down the request of the client to view any particular information, owing to the disobeying of the rules listed under the hypertext transfer protocol. Due to this reason, the clear and concise understanding of the request by the web server could not be established and as a result of this, the HTTP 404 bad request error is often displayed.

Most of the times, the occurrence of a HTTP 400 bad request is suggestive of a bad programming practice at the client’s end or the end of the web server. Such bad practices can be of various different types. At the client’s end, one of the major reasons behind the HTTP 404 bad request’s appearance is due to the incorrect typing of the URL ofthe web resource by the user. In such circumstances, the web server is unable to map the URL request with the address of the desired resource and as a result, it terminates the request. Thus an easy way to rectify the error occurrence in this case is to carefully type the URL of the web resource being requested.

Though it is rarely a reason, but there are situations when such a HTTP 404 bad resource error occurs due to some inherent disabilities of the web server of the website requested. If this is the case, the only possible solution is to notify the webmasters of the website about the occurrence of this problem. The webmasters of any website can be generally contacted using the following email address: webmaster@websitename.com.

There may be other situation where the resource requested by the client could not be accessible owing to some inherent bug. It is the job of the developers in this case to rectify the problem.

Some of you might be using an Internet plan from your ISP which has limited bandwidth. As far as I know, ALL of the wireless broadband in many countries allows unlimited usage BUT there is a fair usage threshold where once you go over the limit, your connection speed will be throttled to a very slow dial-up speed. I have a wireless broadband subscription and they offer two types of plan which is 384Kbps or 3.6Mbps. Both package allows you to download stuff at maximum speed but once you reached 5GB limit PER month, then you’re screwed with a really slow speed. Honestly it doesn’t make any sense to subscribe a 3.6Mbps download speed when you can only use 5GB of the bandwidth per month. The worst part is even the uploading bandwidth is counted to the usage. At least they now tell us in advanced that there is a fair usage policy because last time they never expose this information publicly and you can only find it in their really long list of terms and conditions page which no one really reads. When you find out that there is a fair usage policy and file a complaint, they blame you for not reading the terms before signing up. For those that are subscribed to an Internet connection package which has limited bandwidth usage, it is important that you keep track of your bandwidth usage. Here’s a free internet traffic monitoring software that works.

iTraffic Monitor is a network monitor and reporting tool. It provides real time graph of network traffic. Detailed stats provide daily/weekly/monthly/yearly stats. Stop watch, Session stats.

Monitor and review your Internet or network bandwidth usage with ease

How fast your internet connection? We can graph it for your review

How much data do you transfer? We show you a real-time graph or numerical display, as well as daily, weekly, monthly, or yearly reports

Requires minimal desktop space and system resources

This is how iTraffic report looks like. It’s easy to read and nothing too fancy or complicated.

iTraffic Monitor is relatively new as this is their first version released on 4/22/2009. A few small bugs here and there such as copying the report to clipboard generates an access violation error but it’s no big deal and hopefully they’ll fix it in their next release. What I like about iTraffic Monitor is it can filter out local network traffic or traffic between specific IP addresses. This is very important for people connected to the internet via a local area network (LAN). Very few network monitors can do this and the ones that do usually is a shareware that cost money.

This software is free and takes less than 2MB memory while monitoring your bandwidth usage. Claims to work on all Windows.

Regaining Disk Space is something anyone would love, because who would like to see a ‘Low Disk Space‘ error regularly on their PC, when there are ways to remove useless stuff and use the same space to store some useful files. We have previously covered several articles which can help you in allotting space in your hard drive to better stuff and save yourself from buying new Hard Drives or upgrading the current ones.

By just checking to view Hidden Files and visiting your Windows Folder, you will find tens if not hundreds of some folders which can really confuse you and make you feel that your PC has got corrupted or has been attacked with a virus, but you need not worry because all the $NTUninstall Folders you see are created after approval from you itself and there is no real need to panic regarding this. Now lets see how were these created and can we get rid of these numerous folders.

Whenever you Activate the Windows Update feature in your Computer, the Operating System will connect your PC to the Internet and install Service Package along with lot of updates which are installed freshly or else by replacing older files with newer versions. If you carefully see how the Windows Update is performed you will find that generally a backup is taken after which the Update process is completed and this is the reason these folders are created. These are created with a Prefix of $NTUnistall followed by the Update version or code name. You can directly delete these folders but before you this you need to know that some of these can be important folders too because they could have been recently installed and because of this the deletion of important backuped files can lead to PC issues and if you plan for a uninstallation of any Hot Fixes you will find that the PC wont even restart and give you a error with no solution for the same.

Hence in order to make sure you are going for a complete uninstall, its recommended to use different utilities which can remove the corresponding Registry Entries for these folders and also if you delete these folders, by any means you wont be able to Uninstall the Windows Update which is why i would not always recommend you to delete the $NTUninstall folders. Still if you are keen to do this job here is the procedure.

You can directly visit the Windows Folder, then click on the Tools> Folder Options > View > Check on Show Hidden Files & Folders and then list folders by type. Note the Suffix of each NTUninstall folder which has a small KB Number, make a note of this and delete the folder. Next open Regedit via Start > Run > regedit , and in the Registry Editor, you need to expand.
SOFTWAREMicrosoftWindowsCurrentVersionUninstall following which you need to delete the subkey [name/KB number , then Expand SOFTWAREMicrosoftWindowsCurrentVersionApp ManagementARPCache & Delete the subkey [name/KB number]. The above option is going to perfectly delete the folder and its associated Registry File, but because of this you wont be able to roll back or uninstall the never update and if you want to fix this you need to visit the Control Panel > Add/Remove Programs and under this you will find a list of all the updates installed on your computer. These are generally shown after you select a option on the Top Right ‘Show updates’ after which a list of all the updates are shown along with the installation date, Click on Remove to uninstall the complete update and fix everything.

Now you know how to use BitTorrent and you're busy downloading all sorts of good stuff. Now it's time to explore some more advanced BitTorrent options, like remotely controlling your downloads from any computer.

For the full-fledged BitTorrent geek, remote control means setting up BitTorrent on a home server that runs continuously in the background. Even if you don't want to delve into home server setups, remote control tools have other uses.

Say you're at the office and you want to see if the latest episode of Lost is going to download completely before you get home. Well, it's no problem if you're using a web-based torrent interface.

Software

If you you use Torrent for downloads then you already have all the software you need. If not, you'll need to grab a copy of either µTorrent (recommended for Windows) or Transmission (recommended for Mac users). Both applications offer web-based interfaces.

In either case, you'll need to activate the web-based interface.

µTorrent for Windows

For µTorrent 1.8+ just head to the preferences panel >> Web UI and check the "Enable Web UI" option. Also be sure to set a username and password for a modicum of security.

You can also set a custom port to connect to from the preferences. If you choose to do this (for example, to get through your router-based firewall), make a note of it. We'll follow up on this later.

Transmission for Mac

In Transmission head the preferences >> remote and check the enable box. Also make sure to set your username and password to limit access. Transmission uses port 9091 for its web interface, though you can customize that if you like.

If you happen to know the IP addresses of the machines you're most likely to connect from (for instance, your PC at work) you might want to consider only allowing those machines to connect. This slightly negates the access-anywhere aspect, but it provides much better security. Just add the IPs you'd like to allow to the IP whitelist (also note that both apps support blacklists as well).

Using it

Now that you've got the web interface running, fire up your favorite web browser and point it to the proper address:

• µTorrent address: http://localhost:port/gui/

  

• Transmission: http://localhost:9091/transmission/web/

  

  Regardless of which client you use, you'll notice the web interface is basically an HTML skinned version of the desktop client. It looks and acts just like the desktop client. Most of the options are even the same.

Access Your BitTorrent Client From Anywhere

Now, you have access to torrent downloads through a browser on your local network, but what you want is access to our downloads through any browser from anywhere. To do it, you will need to change the URLs listed above from localhost to whatever your IP address is.

Static IPs

If you happen to be blessed with a static IP address, then all you need to do is find out what it is. To check your IP, the easiest method is to simply visit myipaddress.com. Once you have your IP, you should be able to connect to torrent client by using the addresses above -- just replace localhost with the numbered address from myipaddress.com.

Dynamic IPs

If, like most of us, you have a DSL or cable modem you probably have a dynamic IP address. If you're not sure you have a static IP or a dynamic IP address, follow these instructions.

Cable, in particular, tends to not change IPs very often. When they do, there's nothing's worse than thinking you have access and suddenly discovering you don't. The solution is to set up a static IP that forwards to your dynamic address.

To set one up, head to DynDNS.com.

Once you have a static DNS setup, connect using the addresses above substituting your new static IP for localhost.

One-click remote download with µTorrent

If you use Firefox, you can make torrent links automatically download remotely with µTorrent. For that you need to install the Greasemonkey add-on and then the Add Torrents to µTorrent userscript. That userscript needs to be edited with the proper configuration for your µTorrent host (hostname, port, username, password).

Conclusion

And there you have it -- anywhere access to all your torrent downloads. Now you can manage, tweak, stop, start or just check in on your downloads from any internet-connected machine.
