I have a .jsp page with a button that is supposed to forward the current HTTP session to a new page (performing the same function as a form submit button, except without creating a new session). The button has an onclick action of "buttonAction() ".
I then have a javascript function for it that I want to use to go to a new link with the same session. I tried setting the window.location , but this does not forward the session. Is there a javascript command that allows me to do this? This seems like an easy fix, but I'm going crazy trying to find ANY information.
Thanks if you can help, or can point me to any information that would help.

I have also thought of using a Java method in the .jsp page, but I do not know how to access the request and response from a <%! public void buttonAction() { } %> method. I can access the request and response in a <% scriptlet %>, but not within a <%! declaration %>.

anytime window.location .href changes, the page is redrawn.
possible workarounds:
1. use a master page with 2 fullscreen iframes that 'leapfrog' eachother, passing the state using top. uh top.document.ca che for ex..
2. use ajax to redraw body.innerHTML.
3. save all session data to a cookie, IE xml store, FF2 globalStorage, etc.
-bind body.onload to a loader, and onunload to the saver.
4. you can pass 2kb to the right of a "?" in the url.
5.use the clipboard to persist.
6. submit all session data in the page request, shadow it back in the new page.
7. use cookies to store values.
8. use a combo of sessionStorage and ie history persistence.
9. use a hidden iframe that changes location while the viewport remains.
10. if none of these work for you, there are a few more options.
Thanks for the generous reply rnd me, these are a lot of good suggestions that I will look into. I have never used Ajax before, but I get the feeling that maybe I should check it out.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
