Error Message: HTTP 414 - Request - URI Too Long (248061)
The information in this article applies to:
- Microsoft Internet Information Services 5.0
This article was previously published under Q248061 SYMPTOMS
When you connect to Internet Information Services (IIS) through a browser, you may receive the following error message:
HTTP 414 - Request - URI Too Long
CAUSE
The server is refusing to service the request because the Request-URI is too long. This rare condition is likely to occur in the following situations: - A client has improperly converted a POST request to a GET request with long query information.
- A client has encountered a redirection problem (for example, a redirected URL prefix that points to a suffix of itself).
- The server is under attack by a client attempting to exploit security holes present in some servers that use fixed-length buffers to read or manipulate the Request-URI.
IIS checks the string length of the URI and does not service a request when the URI is longer than expected. This is by design.
