Niall,
Thanks for your response.
-I configure Log4Net at startup in the Global.asax file with the
ConfigureAndWatch method.
-If I cause an error via the proxy, I receive the error and the email
subject appears as "AppName Exception - Log4Net Generated". When I
cause the error not via the proxy I receive the error and the email
subject appears as "SERVERNAME AppName Exception - Log4Net Generated",
as it should.
-I ran a test as you requested, creating an aspx page with the following
command: <%=Environment.GetEnvironmentVariable("COMPUTERNAME")%>. On
both the proxy and non-proxy calls, it correctly returned the value of
the COMPUTERNAME environment variable. So it would seem this is limited
to Log4Net, not ASP.NET, but then again, who knows...
Thanks again,
Leo

Leo,
You you supply some extra information:
- Are you configuring logging on every request, or just once on startup?
- If you cause an error via the proxy and one not via the proxy on the
same run do you get the same behaviour?
- Would you, in your code, try to access the COMPUTERNAME environment
variable in both these cases and see if it is set as you would expect.
