I didn't get a chance to read all of this, but I've got
recommendations for "dynamic" javascript.
Try to separate the javascript into its own file accessible from the
outside world. Be sure to add HTTP headers which indicate when the
.js file was last modified and how often the cache should be
refreshed. This will reduce the number of times the browser will hit
the .js file, resulting in a faster page load time.
Try to read the entire RFC 2616, but if you don't have the time, peek at these:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.15
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.18
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.29
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.21
