 |I use a client browser ( Internet Explorer) to access this proxy . I do get a prompt to Authenticate the Delegated proxy. After keying in the same , I receive one more prompt to connect to the Upstream Proxy . After I enter the required aunthentication I get amessage saying " not able to connect to the required proxy using Delegate.

If you need to control proxy-authentication for chained-proxies, from
the client with different authentication for each proxy, it is not
supported clearly by the specification of the HTTP protocol.
When your upstream-proxy requires proxy-authentication as a pair of
username:password like "user:pass", it can be generated by DeleGate
like this:


Or if your upstream-proxy accepts the same authentication which is used
for DeleGate, it can be forwarded like this:


See the reference manual for more details.
