that really can't be done. Becos there is no way to clear the history cached on the client-side by the user.

What you can do is to use javascript to open any links found on your page, so there will only be ONE reference to your site.

<script>
function replaceWindow(szURL) {
 window.location.replace(szURL);
}
</script>

html syntax
============
<a href="javascript:replaceWindow('user.html');">Log On</a>


from msdn
==========
Replaces the current document by loading another document at the specified URL.

Syntax

location.replace(sURL)
Parameters

sURL Required. String that specifies the URL to insert into the session history.

Return Value

No return value.

Remarks

When a document is replaced, it is also removed from the history object. Moreover, the user interface navigation methods, such as the Back and Forward buttons, will no longer access the URL.

and if a user types in a url to your site, and has come from other sites, the BACK button is still clickable.

The history collection is read only.  What b1 gave you is the closest control you re going to get.  The other option is to open a new window and the use location.replace to prevent the accumulation of a historical trail.

Just to expand on Cd& -- you'll prevent a historical trail for THAT WINDOW ONLY. The history for the main browser window will not be affected.

Thanks fot the info B1.. I dont't like it but thanks anyway.

Is there a way to disable the back-button(and its functionality, I mean als disable the backspace etc to go backwards in history) and write my own back-button with which i CAN control the history.

short of opening a new window and disabling the the contextmenu via
document.oncontextmenu = function () { return false; },
you can not really do that.

You cannot control a user's history via script. It's considered non-doable at this point in time. It is also a security feature to some extent.

Sure! Write a new browser that does exactly what you want, and get everybody who might possibly want to ever view your site to download and use it.

Short of that, no.

There seems to be a relationship between questioners who want to override security and user preferences to violate their right to use their browser the way they wish; and grading histories that reflect a lack of respect for experts. Maybe it is just coincidence that the lack of respect appears general.....

To prevent posting a form twice, I use this technique.

Upon success, my script returns only this instruction, if failed, return a normal page.

<script>
history.go(-1);
location.replace("success.html");
</script>

tested in IE 6 only
