Hi,

Is it possible to Cache images that are in the Global Assets folder? Im performing a Pingdom Website Speed test and all my images are failing the Leverage browser caching section.

I hope this makes sense,

Jon

Do you mean Blobs(Blogs)?

Pingdom will be checking the expiration of static files cache in the browsers. If not set, will mark negative. In theory (I might be wrong) those settings should work pingdom should not have any concern what type of blob have been used. it will be working on contents as HTML, Script, CSS, Images

Hi Jon,

If you're going to use staticFile - don't forget you'll also need:-

<section name="staticFile" type="EPiServer.Framework.Configuration.StaticFileSection, EPiServer.Framework" allowLocation="true" />

Then you simply add the following to your web.config:-

<staticFile expirationTime="8.0:0:0" />

8 Days should be enough to get around the ySlow mininum requirements.

Cheers

Paul
