* Thanks for creating this great plugin!
* When I add the speed boost code:
* [http://forum.ait-pro.com/forums/topic/htaccess-caching-code-speed-boost-cache-code/#post-9707](http://forum.ait-pro.com/forums/topic/htaccess-caching-code-speed-boost-cache-code/#post-9707)
* My website returns a 500 error.
* I have followed the instructions exactly (I believe).
* I have added the custom code to this area:
* CUSTOM CODE TOP PHP/PHP.INI HANDLER/CACHE CODE:
Add php.ini handler and/or plugin
cache code here ONLY add valid htaccess code below or text commented out with
a pound sign #
* Then I created a secure .htaccess file.
* Then I activated Root Folder BulletProof Mode.
* I have successfully added all the other custom code edits advised.
* Here is the exact custom code I added:
* ```
# BEGIN WEBSITE SPEED BOOST

* If you are already using W3TC browser caching then the Speed Boost Cache code
will probably not add a speed increase.
* Things to check:
* If you have cPanel on your hosting then make sure that you have locked your root.
htaccess file on the htaccess File Editor tab page.
* The Speed Boost cache code MUST go after the W3TC cache code in this Custom Code
text box: CUSTOM CODE TOP PHP/PHP.INI HANDLER/CACHE CODE. Note: if you are using
W3TC browser caching then you will probably not notice any speed improvements
since W3TC browser cache code is pretty much doing the exact same thing that
the Speed Boost cache code is doing – Browser Cache.
* w3tc cache code

* I have seen 1 case so far where a web host was not allowing the “Header” .htaccess
directive. So that all code that is using “Header” had to be deleted in order
for that person to use the speed boost code.

* Thank you, I will not add the code then.
* Keep up the great work.
