G'day Ben Thanks for your email.
In regards to why this work around "might" work on some authenticating proxies, is because some proxies are set to restrict certain ports, such as port 80 (http), and the likes, but not all ports. Therefore, some authenticating proxies may not restrict all ports which is why unicast bridging works. It may also have to do with unicast bridging possibly using udp as well. I have seen this work for a site or two. Fortunately, I don't have the restrictions like some others AG sites, therefore, I cannot be sure why it works for some sites, thought I hope it may resolves some issues for other sites. Of course, I would be happy to received any feedback and comments. I hope this clarifies some things. Cheers, Jason. -----Original Message----- From: Ben Green [mailto:ben.gr...@manchester.ac.uk] Sent: Friday, 22 February 2008 8:30 PM To: Jason Bell; ag-t...@mcs.anl.gov Subject: RE: [AG-TECH] Potential Authentication Proxy "work around" for getting Unicast Bridge Listing Hi Jason, Thanks for the info. I have one question though. If an AG3 client has to pass through an authenticating proxy, how would it connect to a meeting in the first place, regardless of whether or not it retrieves a list of bridges? I'm asking on behalf of a user who cannot connect to the venue server 'apparently' due to the fact that you cannot specify a proxy username/password within the network preferences of the client. This same user claims to be able to specify such settings within other applications that bypass his proxy OK.
