I didn't even know if it was possible but google does miracles. just search for "JavaScript page history" and you have the answer.

Code:

<a href="javascript:history.go(-1)">
Go Back
</a>

hi,

I don't have a clue what you mean with tag lib. But I don't think you need it anyway. Your activity page what is the back button suppose to do on that page. And is this the only page where the back button should have a different function or perhaps disabled?
Maybe you could show the result by giving a link

Hi Mr. DJ Kat
thanks for your reply once again!
Actually once a User Enters using Valid Login Id and Password,
he/she comes to an Activity page.
In This Activity Page, On the left Hand side, Modules are lined up with hyperlinks
like for eg
AAA
HR
Sales
Services
....etc. and in the center of the page, it has the links coming under these Modules viz. AAA,HR,Sales,Services etc.....!
now when a user clicks AAA, in the center it will list the links falling under AAA. This all Appears on the Activity page only. Now if one clicks on any of these links ...like say Create User, Update User etc kind of Links coming under the AAA Module, he is then entered into details of that particular link for any transactions or report. Now that Activity page is nt seen nemore. A complete new JSP appears for this.Now if user keeps on navigating thru this BACK link it will once come to Activity page again Rite? now here is the problem tht once user reaches to Activity page ... and clicks on BACK link again on it, he is then directed to the Login page! which i dont want! i want tht if BACK link appearing on Activity page is clicked, user shoeuld be redirected again to Activity page only and nt to LOg in PAge.
Hope i m clear to you! please do let me know if u have ne problesm in getting my Problem. i need it urgently! Pleae HElp me!

what about disableing the back button on the page? If i recall correct your back button is in the footer section
the following code will work propperly

place this in your footer

Code:

<a href="javascript:backButton()">Go Back</a>

this in your head
[code]<script>
var activitypage=false;
function backButton(){
    if(activitypage==false){
        history.go(-1);
    }else{
        //window.location=
    }
}
</script>[code]

and this on your activity page to disable your backbutton(must be placed under the previous code)

Code:

<script>
activitypage=true;
</script>

if you want to reload the activity page change the folling

Code:

    }else{
        //window.location=
    }

into(url probably need to be corrected)

Code:

    }else{
        window.location="activitypage.jsp"
    }
