On a Windows2003 server I have two folders:
The Forum folder is live and actively used. The dev folder contains a number of changed ASP files. Renaming Forum to something else and changing Forum_dev to Forum seems to ignore the changed files. Is there a way to force IIS to clear its cache?
I think I can go through the changed files (in the new Forum folder), make a change and save the file and it's ok, but there are a lot of files...
You could just use brute force and do:
c:\> IISRESET
Not nice but should get the job done.
Are you absolutely sure that it's IIS caching these pages and not the browser clients?
Renaming the root physical folder is probably not helping since the app holds on to that folder. You could name it "pink elephants" it won't care it only needs the name when looking up the folder when starting the application.
The correct and friendly approach is simply to recycle the application pool the application is in. You can do this from the context menu on the pool in IIS manager.
Don't use IISRESET its seriously draconian compared to recycling.
