Description:
------------
We have an application which requires Vary: Cookie for its caching
scheme to work correctly. It's using the header() function to set the
header during the request. With PHP 5.2.9/Apache requesting a page with
both Accept-Encoding: gzip and without will correctly append
Accept-Encoding to the Vary:
--
HEAD / HTTP/1.1
Host: www.easports.com
HTTP/1.1 200 OK
Date: Thu, 11 Mar 2010 01:06:33 GMT
Vary: Cookie,Accept-Encoding
--
--
HEAD / HTTP/1.1
Host: www.easports.com
Accept-Encoding: gzip
HTTP/1.1 200 OK
Date: Thu, 11 Mar 2010 01:07:37 GMT
Vary: Cookie,Accept-Encoding
Content-Encoding: gzip
--
With PHP 5.3.2 the Vary header is overwritten when the content is served
as gzip:
---
HEAD / HTTP/1.1
Host: devsonet.dev.easports.ea.com
HTTP/1.1 200 OK
Date: Thu, 11 Mar 2010 01:10:00 GMT
Vary: Cookie,Accept-Encoding
--
--
HEAD / HTTP/1.1
Host: devsonet.dev.easports.ea.com
Accept-Encoding: gzip
HTTP/1.1 200 OK
Date: Thu, 11 Mar 2010 01:10:53 GMT
Vary: Accept-Encoding
Content-Encoding: gzip
--
The attached diff will make the application work as expected. This was
based on reverting a chunk that had changed between PHP 5.2.9 and PHP
5.2.13. This diff was clearly put in there to fix another bug so it's
*not* intended to be applied; it's just for demonstration purposes
