ob_gzhandler won't work with SSI?

I've enabled ob_gzhandler in my php.ini using the line below:
output_handler = ob_gzhandler

(I believe this means I won't have to put the ob_start line at the top of
every page, right?)


Using this does seem to speed up page load. However, when I include files in
the HTML pages using SSI:
<!--#include virtual="/includes/header.php"-->

the portion of the page that would have been the output from the header.php
script is garbage.

Any ideas?

You're putting gzipped data into an HTML stream that is sent to the
browser non-gzipped. The browser doesn't know that that part of the
HTML stream is gzipped.

Change the HTML file to a PHP file and then require-in the header.php
file. That should work.

Really, if you want everything to be gzipped to save bandwidth, why are
you still using plain HTML files anyway?

There are thousands of HTML files that were created years ago, so renaming
and fixing links is not an option. Is there anyway to restrict ob_gzhandler
to only compress files in a certain directory? For instance, only compress
files in www.domain.com/abc/ and leave everything else alone?

Thank for your help

Oh, I see. Well, I have no idea about the resticting to a certain
directory.

Maybe you could write a PHP script to change all the HTML files to PHP
files and alter the links within them as well. All it has to do is
rename the files have a ".php" extension and then change the links
within to point to ".php" instead of ".html". Of course you should back
up the existing files first, and test the script on a different set of
data, but it seems like it should be possible.

Unfortunately, also not on option since the search engines have indexed the
existing site structure thoroughly and with good rankings.

If I figure it out I'll post in this thread.

Thanks again for your help; at least I know why I was getting the garbage
characters.

SOLUTION:

I ended up using zlib.output_compression as it was recommended over
ob_gzhandler. I put the following two lines in an .htaccess file in the
directory I wanted to compress:

php_flag zlib.output_compression On
php_value zlib.output_compression_level -1

It seems to work fine.

BTW, -1 compression level is the system default. It can range from 0-9 with
9 being the highest compression. I did not see much difference between -1
and 9 so I left it at -1 (default).
