not sure what you are asking?
I just added some step by step instructions directly under that caching code on how to add this Speed Boost code to Custom Code so that folks would not have to jump back in that Forum topic to figure the steps out. ??
1. Copy the Speed Boost .htaccess code into this Custom Code text box: CUSTOM CODE TOP PHP/PHP.INI HANDLER/CACHE CODE: Add php.ini handler and/or plugin cache code here and click the Save Root Custom Code button.
2. Go to the BPS Security Modes page and click the Create secure.htaccess File AutoMagic button and then activate Root Folder BulletProof Mode.
NOTES: If you are using a php/php.ini handler in your root .htaccess file then be sure to copy that php/php.ini .htaccess code directly above this caching code. If you are using a caching plugin that creates .htaccess caching code then you can also add that plugin’s caching code directly above this Speed Boost caching code.
