JSF/ RIchfaces Performance on Google Chrome due to HTTP 304 responses

[amittikoo84]

We are creating an application using JSF 2.0 / Richfaces 4.2.2. The page is loading fast in IE9(3-4 secs) but is painfully slow in Chrome.

Looking at the Network the problem seems to be that for most JSF & Richfaces resources, the browser gets a 304 response but it is talking long(I'm talking minutes) to finally get these resources.

My web.xml:

<context-param> 
<description> Set the max time in miliseconds set on the "Expires" header for a resource rendered by the default ResourceHandler. </description> 
<param-name>org.apache.myfaces.RESOURCE_MAX_TIME_EXPIRES</param-name> 
<param-value>2592000000</param-value><!-- 30 Days --> </context-param> 
 <!-- RichFaces --> 
<context-param> 
<description>Defines in seconds how long streamed back to browser resources can be cached.</description> 
<param-name>org.ajax4jsf.DEFAULT_EXPIRE</param-name> 
<param-value>2592000</param-value><!-- 30 Days --> 
</context-param>  
<context-param> 
<param-name>org.richfaces.resourceOptimization.enabled</param-name> 
<param-value>false</param-value> </context-param> <context-param> 
<param-name>org.richfaces.LoadScriptStrategy</param-name> 
<param-value>ALL</param-value>
 </context-param> 
<context-param> 
<param-name>org.richfaces.LoadStyleStrategy</param-name> 
<param-value>ALL</param-value> </context-param> <context-param
> <!-- If org.richfaces.LoadScriptStrategy is set to ALL, this should be false --> 
<param-name>org.ajax4jsf.COMPRESS_SCRIPT</param-name> 
<param-value>false</param-value> 
</context-param>

Sample request/response for one of the resources(Chrome)

Hey Amit,

there must be something wrong with your caching configuration (might be MyFaces issue).

In theory the browser should use a cached value when 304 response status is retrieved.

Btw this might be relevant:

Thanks

We see this issue with mojaara. The solution listed in the thread involves disabling cache altogether, something I would like to avoid.
