If so it seems the primary issue is this (potentially) impacts all in-protocol URLs vs only those that need to use PortletURLs. For wsrp 2.0 I would add information into the primer suggesting that cacheable resources be accessed via the http proxy mechanism. I would then try and improve in-protocol getResource caching via future extensions/release. -Mike- Stefan Hepper wrote: > As mentioned in one of the WSRP calls currently caching of content > served through resource URLs on the client is basically not possible > for resource that are served through gR. > Reason for this is that the resource URL that the consumer produces > needs to contain all nav state of all portlets on the page in order to > allow the gR call triggered with the URL to produce markup that > contains WSRP URLs again.
