Changing page request

Question

Hello,
Is it possible to change the page request in an onload process?
What I want to do is something like:
IF v_1 = 'some value' THEN
:REQUEST := 'other request';
END IF;
Regards,
Jan

Thank you Arie, for the quick response.
If I understand you correctly you are talking about the request when pressing an button which you can use with validation, after submit processes and page branches?
What I mean is the request you can specify in the url redirect of a button or in the page branch.
I'll give you a detailed explanation of my problem:
I have a page with 3 regions, only 1 is shown at the same time. I have 3 buttons on this page, button 1 has no request, button 2 has request 'B', button 3 has request 'C'.
Region A is shown as default and it's condition is:
where request is not contained within B,C
Region B has condition: request = B
Region C has condition: request = C
Now I want Region B to be the default region under certain conditions, so change the request from null to 'B'.
When I take :REQUEST as default for a textfield I get the expected result, so it's not set to null. But when I want to change the value of the :REQUEST-variable I get an error:
Error      ERR-1002 Unable to find item ID for item "REQUEST" in application
Kind regards,
Jan
