Hi guys
I have a jsp page which takes some parameters from the user when i submit the page i check for some errors and if there are no errors then forward it to another page
Now if i use the browsers back button to go 1 step back it gives me an error
"Data Missing !!!
This document resulted from a POST operation and has expired from the cache. If you wish you can repost the form data to recreate the document by pressing the reload button. "

Then if i again click on Back button of browser then it takes me to the previous page
Can anyone tell me why is it so
Is it bcoz of the Forward tag
And plz can anyone tell me a solution for this
Thanks

Well Well sameera
u have got me wrong i guess
See i get session.isNew() false bcoz i am in the same browser and not bcoz session expiry
What i want is that it should increase the count
I open a browser and type the url
http://sameera:8080/examples/jsp/counter.jsp
and the hitcount increses by 1
now in the same browser i type
www.javaranch.com
i acces 1-2 pages concept is to go to another site and come back again to my page
ie now again i type
http://sameera:8080/examples/jsp/counter.jsp
now the referer is NULL but since the session.isNew() returns false the count does not increase
And i want this also to be considered as a hit

Hi guys
i am using a hit counter
i have created a bean with scope as application and am checking for "session.isNew()"
if this returns true then i increment the counter else i dont.
but the problem is that if i load my page count.jsp and then
go to suppose hotmail.com in the same browser then come back again to my page count.jsp then i want the counter to increment!but it doesnt....
could anyone plz help me with this
Now there is a second option which i am using
I am checking for the referer in the header which gives me the previous page.
i.e
request.getHeader("Referer")
gives me
null if i am putting the url in the browser
if i am coming from the same domain it gives me the following url
http://sameera:8080/examples/jsp/index.jsp
i am just checking that if the referrer is null or anything other than my machine( where server is present Tomcat 3.2.1) i increment the count but in this case
if i open a new browser and put the url
http://sameera:8080/examples/jsp/counter.jsp
it increments the counter but when isay refresh it again increments it which i dont want could any one gimme a solution
plzz
