This is not really something I know a lot about, but I thought
CacheFu is where/what you should look at:
/portal_cache_settings
gives med the option to clear the cache.
I thinkt this works quite OK (although I have only used it with squid)
Den 31. mar. 2009 kl. 00.06 skrev Bill Freeman:
I'm writing a little product to allow plone manager role users to
have Varnish purge its cache by clicking a button in plone.
1. Am I re-inventing the wheel here? That is, is there already
such a product which I haven't noticed?
I already have a tested python module that telnets to the Varnish
CLI, commands the purge, and parses the response.
It seems to me that the proper place for such a button is in the
@@maintenance-controlpanel.
2. Are there good reasons not to put it there?
I can subclass
plone.app.controlpanel.maintenance.MaintenanceControlPanel to add a
an @form.action() decorated method to handle a "purgevarnish"
button, and to specify my template rather than the one in
plone.app.controlpanel, so that I can add a from/fieldset/submit
button.
I don't see any hooks for plugging in, say, a structure provider to
add my form, which is why I'm using my own copy of the template.
That makes me vulnerable to any future incompatabe tempate changes
in plone.app.controlpanel, but I'm guessing that it is pretty stable.
3. Am I missing a cleaner way to do this (still as a new button on
the maintenance controlpanel)?
I don't add any new form data, so I presume that I can use the
existing MaintenanceControlPanelAdapter and its registration, just
registering a new browser page that uses my class instead.
4. Are there issues with that plan? For example, am I going to
have to come up with a way of making my registration more specific
than the base one?
Thanks in advance for any help.
Bill
