[richfaces-issues] [JBoss JIRA] (RF-11992) cache bug in portlet

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 Priority: Minor 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 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.
