SYMPTOMS

Consider the following scenario. In Internet Information Services (IIS) 7.0, you run a PHP application. The PHP application depends on the REQUEST_URI server variable. In this scenario, the application may fail.

Note This problem does not occur in IIS 6.0.

CAUSE

This problem occurs because the FastCGI module in IIS 7.0 incorrectly sets the REQUEST_URI server variable. The FastCGI module does not preserve the query string when the REQUEST_URI server variable is used. For example, "index.php?id=12345" is a request Uniform Resource Identifier (URI). However, the $_SERVER ["REQUEST_URI"] variable returns "index.php."
