I've just released version 1.0.10 of PmWiki. This release changes
the headers that PmWiki sends to control browsers' local caches, and
allows PmWiki to not have to regenerate a page or resend it when
the browser already has an up-to-date version in the browser cache.
This somewhat reduces server bandwidth and processing requirements,
and provides a smoother, faster user experience.
To enable this form of caching, set $EnableIMSCaching=1; in a local
customization file. Note that with this value set, PmWiki will allow
browsers to use cached copies of pages until a page (any page) is
modified in the wiki.
In particular, if caching is enabled then hitting reload in a browser
window will not show the effects from changes to local customization
files or page layout templates. This is why the caching is disabled
by default -- so the effects of the cache won't totally confuse new
wiki administrators who hit reload and don't see any effect to their
Note also that this enables page caching in browsers--it does not try to
cache them on the server. There are some user-contributed recipes in the
Cookbook that do various forms of page caching; I don't know if this new
caching feature will interfere with those recipes. Your mileage may vary.
As always, questions, comments, feedback welcome.
