How to send post request with Excel and get result in default browser?

I would like to send a POST (not a GET) request from Excel/VBA and to have the result in the default web browser.

I tried to use :

• Shellexecute but I Don't know how to add POST variables.
• Followhyperlink but it doesn't work with long post request (it's a request with 80 POST variables)
• Querytables and xmlhttprequest but I can't get the results in the defaut web browser (i have the result in EXCEL)

Thank's a lot if you have an idea
