<ReportServerExternalUrl> with SSRS 2005

When we were on SSRS 2000, I had to add a line in my RSWebApplication.config
file in order for people outside our firewall to access our internal report
server. It looked like
<ReportServerExternalUrl>http://xxx.mydomain.com</ReportServerExternalUrl>
We just upgraded to SSRS 2005 and I wonder if I have to add this line back
into the config file to get/keep this capability.
Thanks.I tried accessing my report server after I got home and had no problems so
the answer must be that I don't need to insert this extra line manually into
the config file. That's nice since it seemed an unnecessary step in SSRS
2000.
