Welcome to the Q&A Forum

Yes , this should work.

I use Drupal CMS alot for my sites. It provides a simple .htaccess with mod_rewrite ON and examples. Also, if using drupal you can create alot of rules from the admin part (such as url aliases and 301 redirects) rather than in the file itself. So, you dont necessarily have to be a ninja to tweak all these settings.

Also alot of caching is done through mod_rewrite as when you cache the page to HTML and rewrite the path in .htaccess to use html cache when someone requests given url => speeds up the site , because it will not even need to touch a database and go directly to html file with cached data.

mozBar is just perfect, except it does not show Google PageRank. If it was added - that would be the best seo plugin. At least for Chrome.

You do not have to add onClick event to the link. You may try jQuery and its event binder, such as click(); in your case. Just assign specific classes to these links and do smth like this

$(document).ready(function{

$('.class_with_onclick').click(function(){

//your stuff goes here.

})

});

Sorry if am being too techy
