    Hi pgilpat,

    In IIS7, the “+” could be blocked due to the double escaping is not allowed in request filter. However, the request filter is introduced since IIS7 and IIS6 is really far from the latest version. We can't find any document about this issue. So you need to check whether IIS6 has the configuration like allow double escaping. In addition, considering IIS is using Urlscan, you may need to go to UrlScan.ini and   %WinDir%\System32\Inetsrv\UrlScan to check whether the configuration is blocking the IIS.


    Best Regards,
