Ken Finnigan commented on RF-11992:
-----------------------------------
I just tested with GateIn 3.5.0.Beta2 and while logged in as Root on GateIn,
there is no Pragma header being set in response, so suggested fix would not
work as there is nothing to remove.
As far as I can see there is now only cache-control: no-cache being set in
header for request and response
> cache bug in portlet

> Key: RF-11992
> URL: https://issues.jboss.org/browse/RF-11992
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: core
> Affects Versions: 3.3.3.Final, 4.2.0.CR1
> Environment: jboss portal 2.7.2; Gatein portal
> Reporter: Ivan Ravin
> Assignee: Ken Finnigan
> Priority: Minor
> Fix For: 5-Tracking

> On Jboss and Gatein portal richfaces cant be cached when user is logged in.
> Bug is found for richfaces 3.3.3 but i think can be reproduced for 4.x
> because org.richfaces.resource.AbstractCacheableResource has similar code.
> The steps for reproduce bug are:
> download portlet bridge 2.2 archive
> deploy richFacesPortlet.war from portlet bridge archive (i used jboss
> portal 2.7.2 bundle and GateIn-3.1.0-FINAL-jbossas)
> look at network activity (i did with firefox + firebug, the same result
> on any other browser). Just open page with richfaces portlet.
> When user is not logged in, all richfaces resources are caching well, and
> this is headers returned by server:
> |Cache-Control |max-age=86400|
> |Content-Type |text/javascript|
> |Date |Thu, 26 Jan 2012 17:57:39 GMT|
> |Expires |27 Jan 2012 17:57:39 GMT|
> |Last-Modified |26 Jan 2012 17:42:17 GMT|
> |Server |Apache-Coyote/1.1|
> |X-Powered-By |Servlet 2.4; JBoss-4.2.3.GA (build: SVNTag=JBoss_4_2_3_GA
> date=200807181417)/JBossWeb-2.0|
> But when user is logged in all richfaces stuff come from network every time
> (more than 1.3 mb).
> This is headers returned by portal 2.7.2 when user logged in:

> The same problem with GateIn-3.1.0-FINAL-jbossas bundle, but now only one
> wrong header:
> |Cache-Control |max-age=86400|
> |Content-Type |text/javascript;charset=UTF-8|
> |Date |Sat, 28 Jan 2012 08:54:14 GMT|
> |Expires |29 Jan 2012 08:54:14 GMT|
> |Last-Modified |28 Jan 2012 08:51:11 GMT|
> |{color:red}Pragma{color} |{color:red}No-cache{color}|
> |Server |Apache-Coyote/1.1|
> |Transfer-Encoding |chunked|
> |X-Powered-By |Servlet 2.5; JBoss-5.0/JBossWeb-2.1|
> This header (Pragma) appears only when user is logged in, and again, all
> richfaces resources come through network.
> I did some debug and found that richfaces create good headers, but there is
> some code in portal which put wrong values into real response before
> richfaces. I cant find this code in portal sources, so maybe it is JBoss AS
> problem, or third party component.
> In Gatein portal problem was partially resolved: it overwrites 2 wrong
> headers with values provided by richfaces, but "pragma" header is absent in
> richfaces response, and this way in secured portlets richfaces generate too
> much unnesessary traffic.
> To solve problem for GateIn there is enough to provide empty Pragma header;
> To solve problem for JBoss Portal its required to fix resource headers
> processing in portal code, like it done in gatein.
