Description Andres G. Aragoneses 2012-08-25 07:40:41 UTC
Created attachment 2408 [details]

Done a very simple web project with two endpoints:

1) localhost/statusTextPlain
2) localhost/statusJson?format=json

The code for it is attached as a testcase.

When accessing the statusJson endpoint, it always works, no matter the setup.

When accessing the statusTextPlain endpoint, it only works if it is run with xsp:

Expected results (in MS.NET or Mono+XSP): returns string "OK".
Current results (with Mono+FastCGI): returns "2\nOK\n\n0"

With this patch, result is "2\nOK", so it's still not perfect, but less polluted.

I'll continue to debug to come up with a better patch, or a second patch.

PD: System.Web tests still pass after this change.
Comment 2 Andres G. Aragoneses 2012-08-25 10:31:49 UTC
Ok, the reason why it works in XSP is because the version of HTTP obtained by "worker_request.GetHttpVersion ()" is HTTP/1.0, and that makes it never use chunked responses.

FastCGI uses HTTP/1.1.

This patch is crap, marking it as obsolete.

Further investigation tells me this may be a bug in nginx. Will confirm soon.
