A couple of weeks ago Chris O’Brien – fellow MVP wrote an article on the research of the SharePoint BLOB cache he has done. During that research he has experienced some issues with some of the files not being cached properly on the client causing the browser to request the file every single time. As I’m working with Web Content Management solutions on SharePoint a lot, it definitely took my attention.
After spending a few days on it, trying almost every possible solution I thought I’d found a solution to this issue. Want to know what it is? Read Chris’ article where he discusses the whole thing: More on optimization, HTTP 304s etc. – a solution?
