Not able to cache any pages using WebAcceleration (AAM)
Hi,
I have been struggeling a while with the WebAcceleration module to cache pages. I have not been able to retrieve a single object from the cache.
I have tried both defining the web acceleration policy manually, and using the iApp to create one for me. But I get the same result.
As an example, I want to cache static content as such CSS files.
When I request a CSS file through the VS, I get the X-WA-INFO header value:
[V2.S10206.A62284.P100017.N13694.RN0.U0].[OT/all.OG/includes].[P/0.0].[O/0.1]
This is the output from wainfodecode
V2: X-WA-Info Format Version
S10206: Response was served from the origin web server, because the content was uncacheable.
A62284: Application: /Common/aam_testapp.app/aam_testapp_aam
P100017: Local-policy: /Common/Generic Policy - Enhanced
N13694: Request Policy Node: Includes
RN0: Response match did not supersede request match
UCI hash: 0
Object type: all
Object group: includes
Request served from TMM: 0.0
Request owned by TMM: 0.1
Entity hit count (local/remote): 0/0
Document hit count (local/remote): 0/0
Document not cacheable (negative cache entry).
Reason: Response cache control prevents caching.
Bypass: Content received is not cachable.
Parking: Not parked.
As you can see, it says it cannot cache the content because of response cache control. I assume this is from the originating web server to the AAM/LTM module.
Here is what the originating web server are sending back to BigIP:

If I understand the headers correctly, there should not be any cache-control saying that the content is uncacheable.
What I have tried so far:
- Same setup against a wordpress/apache site. Configured the Expire and Cache-Control in htaccess - still not able to cache any files
- Tried both iApp and manually WebAcceleration settings.
- Tried an WA Application Profile that should cache anything.
Any suggestions on how to move forward is much appreciated!
