Does anybody experienced issue with ISA proxy server, blocking(!!) ScriptResource.axd request to external webserver?
Site is configured on IIS6 and when I check in FireBug, it shows following message:
* Error Code: 500 Internal Server Error. De aanvraag wordt niet ondersteund.
for ScriptResource.axd request.
then part of page is empty and further leads to sys is undefined as JavaScript is not loaded.
Any input is appreciated.
Thanks
Solved. Actually the error code was 50, ISA logging: Request is not supported.
AccessRuleSendAcceptEncodingHeader was the problem in ISA 2004, there is no settings in ISA which will let you set this parameter to true.
What we did is: Create a script to set AccessRuleSendAcceptEncodingHeader to true as per
http://support.microsoft.com/?id=927263.
You can also find script code to disable it again.
