post's prompt

Hello guys,

I'm using HTPostAnchor(src, dst, htrequest) to post a document and it posts
fine, but 
I get this prompt then the response comes back

Please give name of file to save in: (RETURN for
[/tmp/gateway.dll?Transact])

Is there any way I can get the response into a string, and not have this
prompt?  What am I
doing wrong.

Thanks

Fabio
