Well I have almost gotten this to work correctly. One issue I am
running into is that the link that is being created seems to be
filtered. Here is the following link that is created from my service:
app?service=DocDownloaderService&sp=SExhibitor.doc&sp=l2
if i get rid of the 'amp;' in the url the file is downloaded. Any
ideas on how to not have this filtered?
