We have apache servers that proxy content from an application server and also from a legacy web server. We enabled caching using our load balancer, but the caching is not behaving like we expect it to. Here is our setup:
We're setting cache headers specifically for the pages served from our application server using:
<Location ~ /(appDir1|appDir2|appDir3)> Header set Cache-Control max-age=3600,public </Location>
This works fine.
On the legacy server, the sys admin has set this in his Apache virtual host that runs his legacy site:
Header set Cache-Control max-age=0,private,no-cache
However, our load balancers are still caching the legacy content that we proxy.
When we visit http://appHost/legacyDir1 - we see cached content. When we visit http://legacyHost/legacyDir1 - we see the non-cached content. At least in theory, we're expecting to see non-cached at http://appHost/legacyDir1.
Any ideas what we might be missing ... ?
