CA Service Management - Service Desk Manager CA Service Desk Manager


In some circumstances, when an Analyst copies a Change Order, the following error appears:

HTTP Error 404.15 - Not Found

The request filtering module is configured to deny a request where the query string is too long.
Please see the new attachment.

This problem has been reported with users running Fire Fox 26 so far.


Release: CA Service Desk Manager 12.1 and higher


Refer to the following Microsoft documentation:

Request Limits <requestLimits>


The <requestLimits> element specifies limits on HTTP requests that are processed by the Web server. These limits include the maximum size of a request, the maximum URL length, and the maximum length for a query string. In addition, the<requestLimits> element can contain a collection of user-defined HTTP header limits in the <headerLimits> element, which allows you to define custom settings on HTTP headers."

The document mentioned provides explanations on what to change in IIS to accommodate the string and resolve the problem.

Additional Information

This situation has also been seen in instances where an end user was editing an Activity Log comment and the URL being passed exceeded character limits set on the backend web server.
