A wish for a Mathopd feature

A feature sometimes offered by HTTP servers is "post dating" the expiration 
of content with the "Expires" header.  The benefit of this for highly 
static content, such as Mathopd is so proficient in delivering, is that 
users' web browsers will then not even bother connecting and issuing 
"If-Modified-Since" requests which require the server to almost always 
return a "304 Not Modified" response.

If an option could be added to specify the number of minutes or hours in 
the future for content expiration, perhaps with wildcards so that certain 
directories or certain content types could be given differing expirations, 
it could make Mathopd perform even faster in many situations.

Thanks for listening,
