Hi Olli, What OS and apache version are/were you using? Also Windows? Also 2.2.x? (Secretly I'm hoping that all will be better on *n[iu]x) Spil. On 14/11/06, Kirchel Oliver <Kirchel@xxxxxxxxxxxxxxx> wrote:
Hi, I think we had the same error. "The DMZ1 proxy is connected via ssl, the other connections are plain http." Try to connect "the other connection" via ssl, too. That was our solution.

Hi all, Spuriously we get "Server not found or DNS Error" in Internet Explorer for a site that is reversed proxied with Apache. Please find a txt export of the pcap dump attached. What seems to happen is that the reverse proxy returns FIN, ACK on the 3 connections from IE and subsequently a RST. This then triggers IE into displaying the "Server not found or DNS Error" message. Disabling "Show friendly HTTP error messages" seems to help, but we can't force "the whole world" to change that setting in their Internet Explorer browser (if that were possible for users in a business environment anyway) The setup: Internet Explorer -> Reverse Proxy DMZ1 -> Reverse Proxy DMZ2 -> Application Server v.v. The reverse proxies have simple proxy rules like ProxyPass /b2b_portal/ http://dmz2web.domain.com:8080/b2b_portal/ <Location /b2b_portal/> ProxyPassReverse /b2b_portal/ </Location> and on dmz2web ProxyPass /b2b_portal/ http://app1.domain.com:80/b2b_portal/ <Location /b2b_portal/> ProxyPassReverse /b2b_portal/ </Location> The DMZ1 proxy is connected via ssl, the other connections are plain http. Anyone experience this before and/or can explain this behaviour of the apache reverse proxy? (2.2.3-ssl running on Windows 2003) PS. We used IIS as reverse proxy before and that was fine..... PS. No such behaviour using Firefox 1.5/2.0 Help is very much appreciated! Kind regards, Spil.
