Turning standarderror's output into a variable

[Paul]

Hi,

I'm wondering how difficult/feasible it would be to change the standarderror function to display error messages within existing vb pages instead of on a separate error page.

My concern is that with no-cache headers enabled if someone attempts to post and has an error, pressing back will cause them to lose their changes. What I'd like to do instead is put $error at the top of newpost/reply pages and should there be an error, display it there, but pass any submitted variables to the newreply/newtopic pages (i.e. username/password/subject/message/etc).

I've been toying with this idea for a while and wanted to get some feedback. I know vB3 uses a similar system, but I've had a lot of users complain about lost posts and I'd like to devise a workaround until then.

Thanks,
Paul
