问题 My Google-fu hasn't revealed what I'm looking for, so I'm putting this one out to the crowd. Coming from an ASP.NET development background, I'm used to having the Application and Cache collections available for me to stash rarely-modified but often-used resources (such as lookup rows from a database or the contents of static XML documents) in the memory of the web server, so I don't have to reload these often-used items during every request. Does PHP have an equivalent? I've read up briefly

问题 I am working with download async images. I get a lot images from my webserver but all are temporary and I won't cache any of them.

问题 I have recently begun working with AJAX-Enabled WCF, and have been plagued with this .NET caching issue - Could not load file or assembly App__Web__hamznvwf I was having issues with this 4 to 5 times a day on my server (Win 2003) - see first post So I moved my files off of the server and started running the project locally (Win XP).

问题 I am using asp.net mvc and have a view that displays an item and a view that allows editing an item. When the user submits an edited item, it redirects them to the view for that item. The changes are not being reflected when they are redirected because the item view is being cached. The view item page can also be edited inline and then a submit button uses javascript to submit and then refresh the page. I've noticed that stackoverflow somehow makes this work when you edit an item, it
