Re: loading plain files

I ended up simply looking up the file myself as a resource. I really  
like the header suggestion ... I cache the contents in memory but your  
http header suggestion even helps with the bandwidth as well.

A quick question on using Freemarker again ... I could easily start  
and end the file with a <#noparse> block. For instance - I want to  
load JQuery.js. I've no idea what they include in their distros ...  
but I can easily add the noparse directive to the top and bottom of  
the files they distribute.

Would that be ok?

Would I be safe in assuming that Freemarker would only read that file  
one time? And that for the most part, the noparse directive would  
speed up how it is served everytime?

I not worried about blinding speed - I just want this to scale  
predictably/well.

Thanks,

-Luther
