Using arr url rewrite for a proxy server behind a netscaler load balancer. Currently using ssl-bridge so cert is on proxy server. Everything works. Switched to ssl offloading and 1 of the 12 url rewrite sites failed with 500.0 64 error.
MODULE_SET_RESPONSE_ERROR_STATUS
Warning ModuleName="IIS Web Core", Notification="BEGIN_REQUEST", HttpStatus="500", HttpReason="Internal Server Error", HttpSubStatus="0", ErrorCode="The I/O operation has been aborted because of either a thread exit or an application request. (0x800703e3)", ConfigExceptionInfo=""
Response was:
<h3>There is a problem with the resource you are looking for, and it cannot be displayed.</h3>
Nothing in event log. Cannot determine why this 1 site failed yet all the others continued to work fine. Besides this is just url rewrite so the ssl switch should have no affect on it.
Any help or suggestions would be appreciated.
Included part of the failed trace file with identifying info modified.

There may be a problem on the server running IIS. You must set the correct .NET version in the IIS application pool, and also check whether you need to run the application pool in 32-bit mode. In addition, you also need to set the appropriate permissions
for the application pool identity on the application pool. If your application is running in SSL mode, please make sure it has been configured in web.config.

The problem was that for the website I had Require ssl checked along with ACCEPT for client certs. By setting Client certs to ignore fixed the problem. I don't know why Accept would be an issue but we don't use client certs on this website.

Hi msarrgroup,
There may be a problem on the server running IIS. You must set the correct .NET version in the IIS application pool, and also check whether you need to run the application pool in 32-bit mode. In addition, you also need to set the appropriate permissions for the application pool identity on the application pool. If your application is running in SSL mode, please make sure it has been configured in web.config.
Best regards,

Thanks for the suggestion samwu.
The problem was that for the website I had Require ssl checked along with ACCEPT for client certs. By setting Client certs to ignore fixed the problem. I don't know why Accept would be an issue but we don't use client certs on this website.
