httpd.conf for dummies - migrating your htaccess file

[Asia_Expat]

A good many site owners manage their own server and have access to their httpd.conf file. I've long wanted to migrate the contents of my htaccess file to the httpd.conf file for the efficiency gains... and the learning curve of doing so. One of my goals of running a website was to learn the trade.

I've been far to fearful of breaking something to touch the httpd.conf file until now. I'd like to post my htaccess file in the hope someone will have the time to talk me through the migration, writing a step by step guide, what should be adjusted (and why) etc etc...

... As there are very few people that have as profound a knowledge of Apache as Jim, the moderator of the Apache forum, many of us, inclusing myself use a virtualhost control panel, in my case, cPanel, so when I do this, I'll talk about the results and try to list the issues I faced, such as the risk of losing the changes made upon a server restart, or Apache rebuild...

My htaccess is posted below... who'll help me?...
