Description David Schmitt 2014-03-28 04:23:24 UTC
System.Web.HttpRequest.IsLocal tries to System.Net.IPAddress.Parse the output of worker_request.GetRemoteAddress, which is not an IPAddress when being hosted on a unix socket.

Either delegate the whole check into the worker_request, which IIUIC is a socket specific implementation, or evaluate the REMOTE_ADDR http env variable.


Here's the exception:

System.FormatException
An invalid IP address was specified.

Description: HTTP 500.Error processing request.

Details: Non-web exception. Exception origin (name of application or object): System.
Exception stack trace:
at System.Net.IPAddress.Parse (System.String ipString) [0x00000] in <filename unknown>:0 at System.Web.HttpRequest.get_IsLocal () [0x00000] in <filename unknown>:0 at System.Web.HttpRequestWrapper.get_IsLocal () [0x00000] in <filename unknown>:0 at System.Web.WebPages.WebPageHttpHandler.ShouldGenerateSourceHeader (System.Web.HttpContextBase context) [0x00000] in <filename unknown>:0 at System.Web.WebPages.WebPageBase.ExecutePageHierarchy () [0x00000] in <filename unknown>:0

worker_request.GetRemoteAddress does it actually right and returns $REMOTE_ADDR. This was a setup error on my side.

Thanks.
