Fixed In Version:	curl-7.19.7-43.el6	Doc Type:	Bug Fix
Doc Text:	Previously, libcurl returned wrong value of the CURLINFO_HEADER_SIZE field in case a proxy server appended its own headers to the HTTP response. An upstream patch has been applied on libcurl sources to fix calculation of the field. Now the returned value is valid even if proxy headers are appended.	Story Points:	---

Description Stefan Heinzel 2014-11-06 14:39:41 UTC

Description of problem:

Sourceforge bug id -> #1204 -> http://sourceforge.net/p/curl/bugs/1204/

###
See https://github.com/bagder/curl/pull/60

Often times proxy servers add their own headers (like HTTP/1.0 200 Connection established) to responses on their way back to the client. The size of these headers was not taken into account when calculating CURLINFO_HEADER_SIZE before the change from this pull request.

The problem can be reproduced quite easily using the test program from https://gist.github.com/mj/5102778. In our case the proxy server at proxy:8080 was the default Squid that ships with Debian stable.
###


Version-Release number of selected component in my case:

   # rpm -qa |grep curl
   curl-7.19.7-37.el6_5.3.x86_64
   libcurl-7.19.7-37.el6_5.3.x86_64
   [...]

   # curl --version
   curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.15.3 zlib/1.2.3 libidn/1.18 libssh2/1.4.2
   [...]

How reproducible:

Use curl to connect to URL through proxy server.
