[PATCH] Cache improvement using ESI invalidation protocol





------- Additional Comments From g-froehlich@gmx.de  2002-04-19 16:44 -------
Carsten, all,
I've some serious concerns about this patch! I hope I don't
offend somebody seriously:

(1) It seems like a workaround for an other problem.
(2) I don't think it's usefull to add a new core component like
the Cache Invaldator Server with a extra background thread,
which runs all the time, is used seldom and only for one special
problem.
(3) Logon to the Cache Invaldator Server, to a internal core Cocoon 
package seems to be a security issue for me and not well designed.
(4) For me it seems like a nice try to bypass some dev. problems in
a quick way.

When I understand the problem right the dev. above is trying to invalid
his generated pages direct in the Cocoon caching system. 
--> generates a page (from XSP logic)
--> checks the ExternalCacheValidity (from XSP logic)
--> ExternalCacheValidity requests Cache Invaldator Server 
(with Logon defined in the cocoon.xconf)
--> return true/false if Key valid/invalid

I don't understand the problem fully, but the architecture of this 
solution I don't like. There must be a more elegant solution.

So I'm -1 to add this patch!

Please correct me if I'm wrong!
