There was an error in my own POST:

on step 3, it should be:
3. In your link put href="javascript:document.myForm.submit()".

This is a safe way to use long arguments, since IE only supports about
2048 bytes in the URL. But anyway if you have many Kb to send in a
URL you can always redesign your application to keep data on the
server side using %udat, as suggested.

Sorry for the mistake,
