Description:
------------
If configuration of zlib.output_compression
zlib.output_compression_level is seeded in a php.ini, not at all there are a header "Vary". RFC 2616 section 14.44 requires own.

It is the same problem as discribe in http://bugs.php.net/40325
ob_start('ob_gzhander') is not the only way to start output compression.

And as was mentioned in bug #40325, it was fixed in HEAD (as in: PHP 6) but the fix was not possible to be merged to 5.2 branch.

May you have kindness and have a look at source code? Thanks!

Now hander ob_gzhander sends the HTTP header. It shows you: It is possible to merge into 5.2. You are able to do so as well.

Feel free to provide a patch. Otherwise -> Wont fix. 
Do not reopen this before discussing with mike@php.net about it..

Last time when I brought you a patch the result was no fixing. Your reaction: Deleting the bug report and avoiding the problem own year later.

And now I, sorry _I_, have to turn to mike to help you again? I hope you are able to pick up my e-mail address form the messages, if you are interested getting a fix.

All is said.

It works now. Thanks, but why you fix it this way?

zlib.c

Use php_enable_output_compression() as standard out put only and put all HTTP staff into it call it from PHP_FUNCTION(ob_gzhandler). Status now is functionally a dupe of code lines:

970 -> 987 and 1059 -> 1075
