Dashboard with link to portal with username and password

Hello

I have to link my flashfile to a portal.

The flash file is stored in Infoview. The link to the report is like:

http://servername:8080/OpenDocument/opendoc/openDocument.jsp?iDocID=2222&sType=swf&sRefresh=Y&mode=full

To get this flashfile to be displayed, I have to be logon to Infoview with username and password.

can I post this username and password directly in the link?

so I do not have to be logon to infoview to get the report?

I want the logon to be done automatic when I press the link.

Thank You
