Microsoft makes no warranties, express or implied. Overview After sending an HTTP request to an IIS server, an HTTP client (such as Internet Explorer) may display the following bad request type of error message: The webpage cannot be found. HTTP 400 Most likely causes: There might be a typing error in the address. If you clicked on a link, it may be out of date. What you can try: Retype the address. Go back to the previous page. Go to Bing and look for the information you want. If the HTTP client is Internet 400 bad request Explorer, and the Show Friendly HTTP Error Messages option is turned off, the error may resemble the following: Bad Request In these scenarios, IIS has rejected the client's HTTP request because the request did not meet the server's HTTP parsing rules, or it exceeded time limits, or failed some other rule that IIS or HTTP.sys require incoming requests to adhere to. IIS sends the HTTP 400 - Bad Request status back to the client, and then terminates the TCP connection. Troubleshooting Methods 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 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
Error 400: Bad Request The HTTP ‘Error 400: Bad Request’ typically occurs when a web server receives a request that it is unable to understand. The cause of this is often malformed syntax. If the request contains syntax that doesn’t conform to the HTTP protocol, the server will generate the 400 error. The request should not be re-sent without modifications. The 400 Error occurs whenever the HTTP search cycle is terminated by the web server. As a result, the client is not granted access to the particular information it requested. This is often because the request does not adhere to the rules listed under the hypertext transfer protocol. Consequently, the client receives a HTTP status code and data stream transmitting the ‘400′ error. How Does The HTTP Cycle Flow? When a client such as a web browser requests a http resource, it goes through the following process: The client receives the IP address for the respective domain as you request, using the DNS system. An IP socket connection is opened to that IP address. Then HTTP data stream is sent as a request through that socket by the client. This request is obtained by the web server, which sends a relevant reply as a HTTP data stream which contains status codes and other data. The web client receives the reply and displays the results. This video provides an visualization of the data flow - http://www.youtube.com/watch?v=Pdqss2GvU5M. Different browsers display different amounts of information regarding the 400 Bad Request error. By default, Internet Explorer shows much more detail than other browsers, and it actually suggests possibilities for the cause of the error. For example, if you open a url that triggers a 400 Bad Request error in Internet Explorer, it will display the message below: If Internet Explorer shows a message with no description of the 400 Bad Request error, as below, that means that the “Show friendly http error message” option is disabled. To re-enable it, click on ‘Settings’, and go to the ‘Advanced’ tab. Put a tick in the “Show friendly http error message” box. Mozilla Firefox and Google Chrome will not show much information in contrast to Internet Explorer. The image below shows the default presentation of a 400 Bad Request Error from Mozilla Firefox. As you can see, Firefox gives you much less information, and doesn't eve
