SYMPTOMS
When a program calls the Urlmon.dll dynamic-link library (DLL) file to obtain the associated file data for a page that is redirected from a POST, the Wininet.dll DLL file performs a second GET to the server on a new session. The additional GET request is performed without the previously assigned APSESSIONID variable, and this causes the session information that is stored on the server to be lost. When the session information that is stored on the server is lost, incorrect output occurs within the client program.



CAUSE
The Transaction Data Object has a reference to the original URL and not the new, redirected URL. Internet Explorer version 5.5 issues a new request that does not contain the APSESSIONID information because there is no cache file for the new, redirected URL.



RESOLUTION
To resolve this problem, obtain the latest service pack for Internet Explorer version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
