Subject Re: [users@httpd] Problem with mod_proxy and chunked content
Date Mon, 17 Nov 2014 09:50:46 GMT
We have fixed this problem temporarily. What I've noticed is that the header isn't there and
inserting it (e.g. with burp or fiddler), fixes the problem. I've then tried to insert the
header in the vhost that acts as a proxy, but the header didn't appear. I think that mod_proxy
strips that header as the last part of the request.

We've now fixed the problem by making sure our load balancer enforces http 1.0 for the requests
that were problematic. Later on we'll take another look at this problem when we have more
time.

Thans Stefan for the hint! ;)

kind regards,

>>> We use mod_proxy to selectively request pages from a second site, the ProxyPass
and ProxyPassReverse statements are in the vhost file. Nearly all requests are OK, Except
for one type of request which can't be handled properly. We use SAML SSO and upon logging
out, the response from a simplesaml service provider is not correct. It is chunked, but is
not parseable. The problem is the chunk part within the SAML Response. This is also visible
in the response (see below). I have googled this and searched Apache's bugzilla, but there
is no solution I've tried that works.
