I’ve just set up a server with Apache 2.2, mod\_proxy\_balancer, and a pack of Mongrels. I’m seeing something I haven’t seen before with this setup. Here’s an example: Processing StoriesController#index (for 80.129.122.251 at 2007-02-21 08:38:10) [GET] […] Processing StoriesController#index (for ::1 at 2007-02-21 08:38:14) [GET] […] These are both for a single request. It doesn’t happen on every request, even from the same client. When it does, there’s a consistent 3-to-4 second delay between them. Looks nasty in the browser:-) Can anybody point me in the right direction? Thanks! –Al Evans ---

If you’re referring to the ::1 address, that’s IPv6 notation. The internet’s not quite running on that yet, but your local network might be 😉 I’d disable / turn that off for now. Sorry no links on that, what linux flavor?

What I’m wondering about is why a single request would get sometimes two responses, separated by 3-4 seconds. I’m sure I must have something wrong (though I’ve used substantially the same config on another server with no problems). But I don’t have a clue where to start looking. > I’d disable / turn that off for now. Sorry no links on that, what linux > flavor? Fedora Core 5. –Al Evans ---

Just thought I’d follow up, in case anybody else runs into this problem. I checked my config, and IPv6 was not enabled on the server. After scrounging around a bit in Apache documentation, I changed listen \*:80 to listen :80 That seems to have taken care of it. –Al Evans
