It's entirely possible that I'm under simplifying this, but why not
configure the browser to exclude proxy for local subnet ips?

Hi Paul,


I don't know that's possible or not, but if the mobile browser have a
auto-discovery proxy tool, you can verify if the login page comes from the
IP discovered and unlock it.


Just a suggestion. :)

Hi,


I have a client who restricts their mobile workers' browsers so they
can only access a single site - the client's citrix access gateway. They
 don't want users directly browsing the Internet out of the office -
because of both malware and AUP concerns. They enforce this by setting
the proxy to the corporate proxy (only accessible in the office),
having a proxy exclusion for the CAG, and preventing users editing the
settings.

This all works fine for use on home broadband (wired/wireless) and 3G.


However, it falls down for Wireless Hotspots. Many of these have a
browser-based login page. The proxy configuration prevents access to the
 login page, stopping the hot spot being used at all.

This must be a problem a lot of people have hit. How do you allow
access to Hot spot login pages, but not web pages in general?

Any suggestions much appreciated,


Paul
