Re: [htmltmpl] [question] efficient use of HTML::Template->new

[Mathew R. <mat...@re...>]

If you use the caching options of H::T, then wont need to care where you =
call new(), as H::T will automatically use a previously parsed version =
of the template from the cache, ie. the impact of call new() on a =
previously parsed template, is nearly zero.

Read up on the caching options within the H::T perldoc; you should find =
one of the type which would suite your application environment.

Mathew
