             Summary: 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)
    Affects Versions: 4.2.0.CR1, 3.3.3.Final
         Environment: jboss portal 2.7.2; Gatein portal
            Reporter: Ivan Ravin


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:

|Cache-Control	|{color:red}no-cache,{color} max-age=86400|
|Content-Type	|text/javascript|
|Date	|Thu, 26 Jan 2012 18:26:49 GMT|
|Expires	|{color:red}Thu, 01 Jan 1970 03:00:00 MSK,{color} 27 Jan 2012 18:26:49 GMT|
|Last-Modified	|26 Jan 2012 18:05:56 GMT|
|{color:red}Pragma{color}	|{color:red}No-cache{color}|
|Server	|Apache-Coyote/1.1|
|Transfer-Encoding	|chunked|
|X-Powered-By	|Servlet 2.4; JBoss-4.2.3.GA (build: SVNTag=JBoss_4_2_3_GA date=200807181417)/JBossWeb-2.0|


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 bridge 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.

Gatein portal overwrite 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.
