I'm running a Piranha CMS based page, using it as a content source in passive mode. While working on optimizing pagespeed i saw that all image requests handled by piranha return the following response headers:
GET /media/4b3b3fa3-ff7b-4af7-81f2-168474edd23f/50/20
Cache-Control:no-cache
Content-Length:52826
Content-Type:image/jpeg
Date:Mon, 17 Nov 2014 11:53:28 GMT
Expires:-1
Pragma:no-cache
X-UA-Compatible:IE=Edge,chrome=1
Naturally, i want these images to be cached where possible. I looked around the code on github and saw that this information appears to be set in /Piranha/Web/ClientCache.cs.
Is there a way to influence the caching headers set by piranha?
