Some things gzipped, others not - why?

I’m noticing that some things are gzipped and others not on my server, despite using mod_deflate. Is there any rhyme or reason to this? There must be!

Here’s a look at what is irking and evading me…

Are you using the main config file, or .htaccess to enable compression? Is it possible a .htaccess in a sub folder is disabling, or adjusting which files are compressed?

Is it only the small files not compressing? There isn’t much point in compressing anything below 2K - you won’t save enough bandwidth to justify the processor overhead.

Apparently it needed to have the cache purged. Somehow now it’s properly gzipping. Thanks for the help and thoughts, guys.

Now the question is how do I reduce all those queries!!! Ugh!!! The graphics need to be optimized (I think using sprites). If anyone wants a job, I need someone to help me with this as I’ve got too much to do and so little time!
