Since the user agent masking is probably not going to happen, I will ask this:
I am in contact with my host about the User Agent for UniUploader. I just switched to byethost, and everything that I have checked seems to be working except uniuploader (and phpuniuploader). I think I can change the user agent for phpuniuploader easily (I can try that tonight).
I have asked them if they can allow a specific user agent for this. Their response was:
"How often. and how many requests will this application be making"
I have no idea what to answer to that. I only have a handful of members that use Uniuploader, so I would assume there would be less than 100 updates per week. How many requests does it make when it checks for addons, etc? Is there anything behind the scenes going on that I don't know about? Thanks.
