| Description | resource summary | RAMCacheForAnonymous patch RAMCache for acting only on Anonymous User connexions. (i.e RAMCache works only when AUTHENTICATED_USER == 'Anonymous User') This is done by decorating ZCache_get and ZCache_set methods of class RAMCache PREREQUISITES For the following it is supposed you know how the RAMCache works. A good starting point is : - The onlime Help of the RAMCache Object in the ZMI. - The Zope Book (search "ram cache") : http://zope.org/Documentation/Books/ZopeBook/2_6Edition/ZopeServices.stx INSTALL Put RAMCacheForAnonymous in your Products directory. Then restart your Zope server. API RAMCacheForAnonymous can be used for other Caches. You have to do:: from Products.RAMCacheForAnonymous import patch_cache import Product.TheOtherCache patch_cache(Poduct.TheOtherCache) This code may live well in the initialize() method of your own Product. COMPATIBILITY Tested with Zope-2.8.5 CAVEATS The class is patched => there is no selection on which RAMCache may be patched and which not. This Products provides a Poor Man cache design. It is not intended to replace a full featured intelligent HTTPCache + squid architecture. But provides an easy and quick way of caching Zope side. You may additionnaly add to your RAM Cache the following REQUEST variables via ZMI : - HTTP_ACCEPT_CHARSET - HTTP_ACCEPT_LANGUAGE BENEFITS The RAM used is very low as this patch takes care of not storing data for any non Anonymous User. Installation is pretty simple. AUTHOR Alexandre SAUVE - mr dot lex at free dot fr |
