Pagespeed is not working for weblogic #976

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Install mod_pagespeed(64 bit) on apache version 2.2.22
2.restart apache

What is the expected output? What do you see instead?
we are connecting to weblogic servers using Apache reverse proxy and we are 
using pagespeed on apache to optimize JS/CSS/images coming from weblogic 
servers or behind apache (Weblogic->Tuxedo)
After so many tries we are able to make pagespeed works for one WL instance - 
gtcd3 but we have lots of similar instances requests being served from the same 
apache. Please check attached file for configurations. somehow pagespeed is 
only working fo gtcd3 but not for any other weblogic instances.

I am attaching "mod_pagespeed_message.txt" which I am getting on the browser 
with /mod_pagespeed_message URL.

Please note that I have tried lots of options and then creating this issue. So 
kindly help to resolve the problem.

Please let me know what could be the problem? Any help would be great.

What version of the product are you using (please check X-Mod-Pagespeed
header)?
mod_pagespeed 1.7.30.4-3847

On what operating system?
Linux 2.6.39-400.214.3.el5uek x86_64

Which version of Apache?
Apache/2.2.22

Which MPM?

URL of broken page

Hi Josh, Hi Matt,

The problem is now fixed. Oracle recommended upgrading the mod_wl plugin to the 
latest version(v1.1). Then mod_pagespeed started working fine.

Thanks for all the help.

Please let us know if this resolves the issue.

Cool.  What are the response headers for 
https://psdevl4sso.corporate.ge.com/cs/tsd3/cache/GE_PT_ORACLELOGO_SWAN_1.gif ?

It looks like you might not be able to find them with wget if they require an 
SSO cookie, but you can get them from the Chrome Dev Tools or Firebug or 
something.

While you are at it, also check the HTTP response headers for 
https://psdevl4sso.corporate.ge.com/cs/tsd3/cache/PSSTYLEREQ_1.css and 
https://psdevl4sso.corporate.ge.com/cs/tsd3/cache/PSSTYLEDEF_SWAN_1.css

I seem to be getting the same "issue". I have an Oracle HTTP Server (which is a fork of apache) as a reverse proxy for WebLogic. Of the 63 images on my home page, 13 are being converted to WebP and the others seem to be untouched. When I search the mod_pagespeed log for any of the images not being touched, I see this same message: [Wed, 14 Sep 2016 15:17:06 GMT] [Info] [12373] Cache entry is expired: http://portal-uat1.smiles.com.br/documents/10282/12619544/BannerHomeMobile.jpg (fragment=smiles.com.br) The headers being returned to the browser are:

Cache-Control:private Connection:keep-alive Content-Disposition:inline; filename="BannerHomeMobile.jpg" Content-Language:en Content-Length:32061 Content-Type:image/jpeg Date:Wed, 14 Sep 2016 15:17:13 GMT ETag:"d920950c" Expires:Sat, 12 Sep 2026 15:17:13 GMT Last-Modified:Thu, 07 Jul 2016 14:56:38 GMT Server:Oracle-HTTP-Server-12c Vary:Accept-Encoding X-Content-Type-Options:nosniff X-Frame-Options:SAMEORIGIN X-Powered-By:Servlet/3.0 JSP/2.2 X-XSS-Protection:1

Any ideas on what I could try? I'm messing with the conf files right now.

Tks

EDIT: After posting I decided to, you know, actually look at the headers. Cache-Control:private means it shouldn't be cached by intermediaries, so that's probably the reason. I'll see if that makes a difference.
