I ran into the same problem. The solution is to send a META EXPIRE tag as part of the
document. Note that using the API to set the expiration date in the header does not
always work! Some braindead browsers (read IE) ignore it. Try this:
<meta http-equiv="Pragma" content="no_cache">
<meta http-equiv="EXPIRES" content="Tue, 14 Dec 1999 10:04:37 GMT">
I am not familiar with the Pragma sub-tag and haven't traced down which one of these
lines work, but they do! Another thing I have done is to create a getLastModified()
method in my servlets. It just returns the current time so that it always looks
modified. Not the best solution. But there is not enough state in
the database to which I am connecting to detect *what* might have changed. So I just
always assume that something has changed (at least for now).
The output of the getLastModified() method gets fed into the meta EXPIRES tag above.
So when I do make getLastModified() more intelligent, the benefit will be passed onto
the meta EXPIRES tag generation code.
Hope this helps.
