Allow option to save user credentials

Hi:

We've developed a site using a Geocortex security store (xml file-based) for several different departments to use.  We have one generic user per department, and everyone in a given department uses this generic user.  The problem is that when launching the SLV or linking to it from an outside application, credentials have to be entered every time.  Please add an option to save credentials so my users can stop thinking I've made life difficult for them on purpose.
