Re: [jQuery] loading js files at the bottom of the page

Try it. Firebug makes it easy to see the order that things are loaded and
how long they take.

I will say keeping script tags in the head makes the body DOM cleaner, FWIW.

Also scripts linked in the head can be cached.

All *external* scripts can be cached, no matter if you include them in 
the head or elsewhere.

Hi Klaus,

When you say cached you mean browser caches them for you *OR* do you 
need to do something else yourself


Cheers,

The browser will cache scripts and css included in the header, but not
anywhere else.

I'd like to know that as well. How would a browser distinguish where 
from the DOM an external file is loaded? Why should images be cached 
then, when they're included in the body only?

That may be true for external style sheets, but only because you can 
only include external style sheets in the head.

I always assumed the css was pre-fetched and cached because of the
http headers (that are derived from the )

Link: ; /="/"; rel="stylesheet"; type="text/css"

is generated by apache when a link is in the head. But I've never
served a page with a fake header to prove it.

You don't have to do anything, this is up to the browser. Of course you 
have to be aware of the response headers that are set on the server. 
These may prevent caching.

To verify that this is not true, simply include an external script file 
in the body and check the response headers for this file for example 
with the livehttpheaders[1] extension.

It reports: HTTP/1.x 304 Not Modified

That means the file is cached. In addition, if you check the Net tab 
with Firebug it will also say "xx KB from cache".

Ehh, guess i shouldnt have sounded so confident with that. I acctually dont
know if thats true, it just seems like thats what a browser should do.
