of course your effort is appreciated and no body say not!!

It is just want to put things right so no one get confused about the major factor that causes pages to perform best

waiting to know how you are going to do this good stuff though... :)

if you can combine all js and css and main images individually together, then it would be great!!

This sounds interesting...

The options to combine all javascript in a single request and all css (2 http requests to serve all) are hardcoded in my test forum.
The misfortune is that I need to learn how to combine all and make a xml file to create a mod.
Because it would be bad for most owners to manually edit php files to implement this optimisation.

My other priority is how can a hacker exploit this.

Wow i don't even mind of getting 40 :D single digit http request getting is max optimize :)
good luck mate

Pretty sneaky there, removing the subforum icon & replacing it with a symbol.

how to notice how many http requests we have before and after this ?

Thanks
