Hi Brain,

>From the description, you'd like to have a aspx page be posted to some
other pages by setting
its <form > tag's "action" attribute, yes?

Generally the ASP.NET web page is designed with "post back" model which
make it albe to program as a windows form and it's not recommended to post
the page to another by changing the <form > tag(as what we do in classic
asp) . However, there are still some other means to implement such
functions. We can make the ASP.NET page's
<form > tag as non runat=server so as to make it able to posted to another
page(just as a normal html page). However, using this means will lose the
features of the ASP.NET pages.

In addition to the above means, here are some other approaches:
1. Some some clientside script to change the form's tag's attributes when
the form's submit event is fired. But if the targe page we want to post to
is also an ASP.NET page, we'd consider some issues with the validation and
viewstate checking of the ASP.NET page. Here is a tech article on using
javascript to post a ASP.NET form:

#Post an ASP.NET form with JavaScript

2. If the post operation (the datas want to post) can be generate all via
code, you may also consider using the webrequest class to do the post ,
here are some references on using the webrequest class to post to a certain
url:

#Requesting Data

?frame=true

Hope these help.
