Try checking the source for javax.servlet.http.HttpServlet. This contains
the code that makes the decision to cache. If you "copy" this logic into
your doGet() method, you can see and control exactly what is happening...
Things i'd check are:
- have you got your browser cache settings right?
- does the VM that JRun is running under have the right time settings? If
you're using the MSVM, it stuffs up timezones...
- does JRun add any headers that affect the situation? you could try
telnetting to the JRun port and doing a GET manually..., and try printing
out all the headers in your servlet...
