Yes, I am currently using the HTML::Template filecache option, but that

it does cache that output, but when I return from runmode 3 to runmode2, it
pretty much executes the whole sub, which accesses the DB to get values to
fill the template variables (in a template loop).
I think you aren't completely clear as to what the cache on H::T does.
It doesn't cache the output (since that could change dramatically based
on the params) it caches the parsed template so that the next time it
won't have to parse it again.
Another problem with using the js back() approach would be the same
drawback with storing it in a session... The user would not see anything
that was added since the first time they did the search. The only
difference between using the javascript and the session is who does the
cacheing - the browser or the server. Either way you run into data
conherency issues.

I would suggest reading the docs on HTML::Template's caching
methods. They may help, but HTML::Template is quite fast anyway.

Hello,
I have a database application which is very similar in structure to the
one given in the C::A example:
run mode 1: search form
run mode 2: access (MySQL) database and display results
run mode 3: detailed information on one item
Each run mode outputs to the browser using HTML::Template. The
application works fine, although I am concerned that when I return to run
mode 2 from run mode 3, it has to search through the database again before
displaying the same results.
Is there a way to get from rm 3 (via a link) back to the _template
output_ of rm 2 without having to go through the whole rm 2 script (which
opens a DB connection, performs a select statement etc. then plugs the
relevant template variables into the template file, and finally outputs the
template to the browser)? I know it can be done with
javascript:history.back(), but what can be done for non-js browsers or
browsers with js turned off? Am I missing something that should be staring
me in the face?
Any help/suggestions would be greatly appreciated.
Mike.
