a proxy is something that you program your browser with and all requests go through that proxy and there's no special programming required on the proxy side. much more canned i believe.<br>
<br>
a reverse proxy allows you to contact a website without having to make changes on the client side, but the proxy has to be configured to do all the re-writing.<br>

I knew Lelio was going to chime in ;)<br>
<br>
It's an interesting note that while none of my financial customers have done this, or use features like secure voice, I have one Edu whose policy is "everything on the network must be encrypted, end of story". The net of this is vastly more time spent troubleshooting
security/encryption issues, and a significant extra workload in terms of additional servers/development work to "Secure" things that aren't secured by their nature (eg; ODBC access to UCCX via informix drivers. While ODBC can be secured/encrypted, the informix
connectivity to UCCX can't be encrypted)<br>
<br>
I digress. While I agree with Lelio that it's not a difficult thing for Cisco to implement, I've yet to see the real-world call for it barring very specific circumstances...and we all know the reality, until it's clamored for by a collective of customers spending
10's of millions of dollars, it's not likely to happen.<br>

rules to disallow certain access based on source, and that may not even work as things like authentication URL's are on the same IP/port on the CUCM - you'd have to do some application layer filtering of URL's.<br>
