Hi All,
A question regarding post method in servlet:
I have an html form for user to input their userid and password, which
invokes a servlet's post method, if the user input some incorrect
information, he will get an error message screen which displayed by this
servlet, the problem is, if the user then click any link from this error
message screen to next page, then click back button trying to come back to
this error screen, he will get a warning like:"page has expired, please
click Refresh button", the user has to click the Refresh button to be able
to see the error message screen again. Does anyone have an idea how can
bypass this warning, and display the error message screen directly?
Thanks in advance.
Bo
