If I use the Blob Cache, are List Item attachments cached in it? Are there any special considerations for using the Blob Cache with list item attachments?

At the point in the API where the blob caching mechanism is invoked, a list item attachment looks no different than a library item ('s a BLOB read). They are absolutely included in the BLOB cache and do not require any special consideration.

Just be sure that the file extensions of the items you are expecting to be cached are included in the Blob Cache setting in the web.config – Dave Wise Jul 28 '11 at 22:23
Yup, extensions are there. I thought this would be the case, but was traversing the file system on the WFE and wasn't seeing any of the things I was expecting to see... – Brian Jul 29 '11 at 11:47
