RedSeed servers will try and force caching for a wide variety of file types:




Cascading style sheets

.jpg, .jpeg, .gif, .png


.pdf, .txt

Pdf documents & text

.swf, .flv, .mp4

Video files

Please ensure that any proxy / content filtering / threat management servers are configured to preserve and obey our HTTP caching headers. E.g.

Cache-Control max-age=15552000, public
Etag "4e5ff0d83b840"
Expires Fri, 21 Mar 2014 21:59:36 GMT



Cacheable RedSeed course content varies in size from C.10mb for small courses with little or no video content up to C.1GB of images and video content for our larger courses. 

Contact for more details about course file sizes. Please set local browser cache size as large as possible (at least 1GB in size) to allow as much of this content to be cached locally as possible.

Please also set any proxy/content filtering/threat management server cache sizes to be as large as possible.

Setting a large (1GB+) local browser cache can have a dramatic effect on the speed of RedSeed to the end user and can reduce bandwidth requirements by up to 95%.



RedSeed servers will try and disable browser caching for dynamic pages and any pages with a content type of text/html such as via HTTP caching headers such as:


no-store, no-cache, must-revalidate, post-check=0,

 Expires Thu, 19 Nov 1981 08:52:00 GMT 
 Pragma no-cache 


As per above, it is important that any proxy/content filtering/threat management servers are configured to preserve these headers.
