The actual reasons behind HTTP 400 errors are several and are a matter of detail discussion. It requires a close understanding of this particular problem and necessary suggestions to opt for a quick solution. Given below are the various causes of “HTTP 400 Bad Request” error along with some suitable remedies:

Downloading the HTTP 400 repair tool is the most suitable procedure to fix this “Bad request” error code. Among all the following procedures, it is the simplest and the most reliable one too.
• When the website name connects us to a server that serves that website no more with that name then the server denotes “Bad request”. If the server is the part of a web-hosting site then we may find several sites enlisted in the section called “Other Website On”. This occurs when after the termination of agreement between a website owner and the web-hosting server the updating of details of this site from the DNS or Domain Name Service remains undone.


To fix this problem one may clear the DNS cache. For this one has to open a Command Prompt and type ‘ipconfig’ or ‘flushdns’ and at last by resuming the web browser. This not only compels our system to verify and find out the server we are looking for and its current address but also alerts us about whether it is a current server that we are using.

Secondly, to get rid of the HTTP 400 errors one may check the archived copy of the object.

• When the Domain Name Service or DNS is temporarily inactive or rather in recess few “deployed proxies” give 400 signals in return.


Using a different proxy can give a solution.

• When our browser has an outdated cookie the computer screen will display message containing the term “malformed or illegal request”.


For fixing this problem, one may try to delete the cookies stored in the computer, which are in relation to this site.

• The requests and the responses which runs through the web server and a web browser are defined by the header lines included in it. These lines are officially unlimited but several servers are there executing and forcing their own limits. As a result, in such cases HTTP 400 error occurs when very long header lines are there.


Header lines like ‘Accept-Language’, ‘Referer’ and ‘Cookie’ are controllable.

However, it is a proven fact that to get rid of this problem one must waste no time to download the HTTP 400 repair tool and resolve the “bad request” error.
