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.

Additional query words: IIS 5
