Verify if a page is gzip compressed

[nic0las]

Hi,

I added a "ob_start("ob_gzhandler");" at the top of my php pages to compress the output using the gZip lib.
But i'm not sure the page is really compressed, since it's completely transparent to the user.

Is there a way to know if the page is compressed or not ?

Plus I just wrote "ob_start("ob_gzhandler");" one time, in the index page of my site, which contains includes for the other pages to be displayed into the index (using "index.php?page=stuff_to_include", you know).

Must I add "ob_start("ob_gzhandler");" on all the pages, even if they are displayed into "index.php", that already contains that function ?

Thanks in advance for your help!

Yes, you can include the header call to the compression routine. There is no need to continually retype it.

As for checking, just create a REALLY big file (say 1 mg+ uncompressed) and place it on the server for testing. If that file is significantly smaller during transfer, you can assume that compression is in fact taking place.

Finally, the method "index.php?page=stuff_to_include" is REALLY bad practise. For example, imagine I insert this:

index.php?eval("print%20/etc/passwd")

I now own your server. Never include code through anything but well formed, static calls placed within your source.
