Report for Many Objects Cannot Be Created

Updated

Problem

A statistical report or multiple reports at the same time cannot be created. The following message appears in the browser:

  • HTTP Error 404.15 - Not Found
    The request filtering module is configured to deny a request where the query string is too long.
     

or
 

  • The length of the query string for this request exceeds the configured maxQueryStringLength value.

or

  • Request failed: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd"> <HTML><HEAD><TITLE>Bad Request</TITLE> <META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD> <BODY><h2>Bad Request - Request Too Long</h2> <hr><p>HTTP Error 400. The size of the request headers is too long.</p> </BODY></HTML>

Solution

The following settings need to be checked and possibly adjusted:

  1. The report call must be made using POST. If the report is called from WebOffice, this must be configured there.
    If the report is called from a data list or an attribute mask, which is called from WebOffice, the data list or attribute mask must already be called using POST.
  2. In IIS, the value for maxQueryString under system.webServer/security/requestFiltering must be increased.
  3. In IIS, the value for maxQueryStringLength under system.web/httpRuntime must be increased.
