Hi all,
I emailed the -users list earlier today thinking I had an issue in a
plugin I was writing but after further investigation I'm starting to
think this is a bug in TS.
Below you will see that TS is returning an error response which contains
both TE chunked and a content length. I think this is because of this
section of HttpTransact::HandleApiErrorJump(...)
if (s->hdr_info.client_response.valid()) {
s->hdr_info.client_response.fields_clear();
s->source = SOURCE_INTERNAL;
}
If I set s->source regardless of valid() then I get the following
(correct) response from TS:
HTTP/1.1 500 INKApi Error
Date: Wed, 03 Jun 2015 20:13:32 GMT
Proxy-Connection: close
Server: ATS/5.1.2
X-Cache: MISS from death-cache
Content-Length: 0
Thoughts? Should I raise a bug?
Thanks,
