flushing output buffer with mod_deflate

I've configured my Apache 2 server (Red Hat 9) to compress text files using
mod_deflate. This works fine and really speeds up things.

However, I have a PHP script that takes a long time to run and needs to
send some status info to browser so the user knows it's running, something
like:

* Processing record 1 of 50...
* Processing record 2 of 50...
* Processing record 3 of 50...

mod_deflate holds all this output until the script ends and once it's all
done it compresses the output and sends it to browser.

I've read the module documentation but couldn't find a way to disable
compressing per directory or per script. I cannot change the MIME type of
the output because I need it to be displayed within browser window.

If you could think of an elegant solution I would really appreciate it.
Well, even if it's not elegant at all :)

You can steer mod_deflate by enviroment variables
http://httpd.apache.org/docs-2.0/env.html#special
and set those by a variety if means
http://httpd.apache.org/docs-2.0/env.html#setting

The larger example at
http://httpd.apache.org/docs-2.0/mod...ml#recommended
shows a line disabling compression for the most common image files
SetEnvIfNoCase Request_URI
\.(?:gif|jpe?g|png)$ no-gzip dont-vary

Prefixing the file name by 'nph-' might work aswell, though, most likely,
its output will lack some HHTP headers.

Eitherway, thereafter you might want to try to get your php script to do
some deflating on each chunk too ...

It works like a charm. I wasn't able to set env vars from PHP but a simple
..htaccess file solved the issue:

<Files my-long-running-script.php>
SetEnv no-gzip 1
</Files>


Thank you very much and sorry for the delay (X-mas and other stuff, you
know :)
