How to Send Request to IIS Server after the Page Displayed

Hi All,

Is that possible that I can send request to IIS Server after a .ASP page is
displayed?

My Requirement is:

Clinet will Fill the Details in one Request Form after the details are
filled then the Request Files will be shown to the user as Link in Another
page. (Currently before Sending the Link Page to Customer I am updating DB
in Different Servers Located Different Palces - So It takes Time).

So What is My Requrement is After the user gives his details - I will
directly display the Link Page and After the Link Page is Sent to Browser
then I will Execute / Update the DB.

How Can I Do that?
Please Help

Thanks
Prabhat
