Hi, This is exactly how I am currently setting the headers, however I don't want to do this on an individual basis for all StreamResponses.
What I'm looking for a is a filter or similar mechanism that can be used to post-process all responses irrespective of whether they are StreamResponse objects or the output from normal components with markup in a tml file. Essentially a filter like the MarkupRendererFilter that works on StreamResponses as well Thanks Ian -----Original Message----- From: cordenier christophe [mailto:christophe.corden...@gmail.com] Sent: 15 October 2009 15:31 To: Tapestry users Subject: Re: Lifecycle of a tapestry request and the MarkupRendererFilter What not using the prepareResponse of the StreamResponse Tapestry interface to set headers ? 2009/10/15 Ian Petzer <ian.pet...@ioko.com> > Hi, > > We do actually have a load balanced caching system sitting in front our > app server, however we control the caching behaviour by setting headers > on the HTTP responses. > > For example in this particular case we need to set: > response.setHeader(CACHE_CONTROL_HEADER, > "no-cache"); > response.setHeader(PRAGMA_HEADER, > "No-Cache"); > > > > > > -----Original Message----- > From: cordenier christophe [mailto:christophe.corden...@gmail.com] > Sent: 15 October 2009 14:58 > To: Tapestry users > Subject: Re: Lifecycle of a tapestry request and the > MarkupRendererFilter > > Hello > From my point of view this kind of caching mechanism should be done in > front > of your application server. > > Regards > Christophe. > > 2009/10/15 Ian Petzer <ian.pet...@ioko.com> > > > Hi, > > > > > > > > I have been successfully using the CacheControlMarkupRenderer from the > > ioko-tapestry-commons > > <http://tapestry.formos.com/projects/ioko-tapestry-commons/> library. > > This is a java class that implements the MarkupRendererFilter and > > Partial MarkupRendererFilter in order to apply caching headers to > pages > > served by our application. > > > > > > > > This is all working wonderfully, however we now have a component which > > is returning a StreamResponse object out of the onActivate method of > the > > component.
