PHP/GD images with mod_deflate

murphymurphy

I am using mod_deflate (w/apache2.0.46 php4.3.2 freebsd5.1-R) and it keeps compressing the images, in my httpd.conf I have mod_deflate set to:
AddOutputFilterByType DEFLATE text/html text/plain text/css

and I send a header with the PHP generated image:
header("content-type: image/png");

so i can't see the problem but still it persists, it does not try to compress static images (image.png or wahtever) only image.php files. It is really annoying as it slows my server down and it is only an aging 233 anyway 🙁

any help would be much appreciated.

hi-liter

you can restrict the compression to a particular MIME type and maybe prevent this problem?

http://httpd.apache.org/docs-2.0/mod/mod_deflate.html

hth? i'm not very familiar with mod_deflate.

i fixed the problem.
I added a second extension to be parsed by PHP, so I could use one for images and one for text/html:
AddType application/x-httpd-php .php .gd

then I copied the recommended settings out of the apache manual and added gd to the list of extenions:

SetEnvIfNoCase Request_URI \
.(?:gif|jpe?g|png|gd)$ no-gzip dont-vary

i can't find any other way to do it, but this seems as good a way as any. It also allows me to distinguish between PHP generated images and text when I analyse my logfiles which is nice.

PS i tried the MIME type thing, but apache seems to treat all PHP as whatever the default MIME type in the php.ini is, anyone correct me here! and sending a content-type header didn't seem to change this.
