I've been pondering something about the impact of cacheing
(both locally and via proxy servers), and its impact on mhonarc
indexes. [...]
Basically, an index page is updated whever the archive is
modified, but if a user has cached an earlier copy of the
index, that won't refclect the changes. So, every time a
user looks at the index, should he/she reload it?
This "problem" occured to me as well when I was developing my
MHonArc archive.
[snipped thoughts about use of the "expires" META tag]
Can anyone help me get my head around this?
Rather than use the "expires" META tag, I used the "no-cache"
pragma. I redefined the appropriated resources (<IdxPgBegin> and
<TIdxPgBegin>) as in the example below:
<IdxPgBegin>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML//EN">
<HTML>
<HEAD>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<TITLE>$IDXTITLE$</TITLE>
</HEAD>
<BODY>
<H1>$IDXTITLE$</H1>
<HR>
</IdxPgBegin>
You can see the complete resource files I use and the resulting
archive by following the links from:
