Error with postback on very large page

[mike.lerch]

I hope I can describe this in a way that someone can recognize it and
help out. I have a page on an intranet which for certain users lists
many many links and for other users lists a only a few links.
Essentially, if you are a user it will show you items relevant to only
you, but if you are an administrator you will see everyone's links and
can poke around. How many links? I just saved the resulting web page
using File->Save and it is 10,263.169 byes, 9.78 MB. A regular user
has maybe a .5 MB file.

Clicks are handled on the server side, and the handler takes care of
expand/collapse as well as redirecting the user to the source of
whatever link they finally click on.

Here's the trouble: for regular users, everything is fine. For the
administrators, everything *used* to be fine. But now, anyone who sees
the maximum number of links gets the following error when they click on
one:

1. They are prompted for a user name and password to connect the the
network resource (which they've already authenticated with and should
not be prompted, and users with smaller pages do are NOT prompted)

2. Nothing happens except, apparently, that the page reloads. They are
not redirected to their link (which is handled in the code with

Page.Response.R edirect("linkte xt", true);

Again, folks with smaller initial pages have no problem: they go right
to their redirects.

Does anyone have an idea of what this could be about? Is there a size
limit on redirects? Any help is appreciated.
