400 Bad Request Request Header Or Cookie Too Large
/> If Internet Explorer’s Friendly HTTP Error Messages option is turned off, the error may error 400 youtube resemble the following: In these scenarios, IIS has rejected the client’s error 400 vba HTTP request because it did not meet the server’s parsing rules, or it exceeded time limits, or failed some other rule that IIS requires incoming requests to adhere to. IIS sends the HTTP 400 – Bad Request http://pcsupport.about.com/od/browsers/fl/http-400-bad-request.htm status back to the client, and then terminates the TCP connection. Troubleshooting When troubleshooting an HTTP 400 condition, it is important to remember that the underlying problem is that the client has sent a request to IIS that breaks one or more rules that HTTP.sys is enforcing. With that in mind, you will want to see exactly what the client is sending to IIS; to do this, capture a network trace https://blogs.msdn.microsoft.com/webtopics/2009/01/29/how-to-troubleshoot-http-400-errors/ of the client sending the bad request. You can analyze the trace to see the raw data that the client sends to IIS, and to see the raw response data that IIS sends back to the client. You can also use an HTTP sniffer tool called Fiddler; this is a great tool as it allows you to see the HTTP headers even if the client and server are communicating over SSL. The next data item you will want to use is the httperr.log file. Beginning in IIS 6.0, the HTTP.sys component handles incoming HTTP requests before they are passed along to IIS, and is the component responsible for blocking requests that don’t meet the IIS requirements. When HTTP.sys blocks the request, it will log information to its httperr.log file concerning the bad request. NOTE: For more information on the HTTP API error logging that HTTP.sys provides, see the following article: Error logging in HTTP API http://support.microsoft.com/?id=820729 It is technically possible, although not very likely, that a client will receive an HTTP 400 response which does not have an associated log entry in the httperr.log. This could happen if an ISAPI filter or extension or an HTTP module in IIS sets the 400 status, in which case you could look at the IIS log for more
