IRC [14:14] <cnk> Does AOLserver 4 not speak HTTP 1.1? or do I just have my server mis-configured?

IRC [16:33] <Dossy> i'm here, but very busy right now
IRC [16:49] <cnk> For the record - and in case anyone wants to jump in with comments. I have been doing some load testing with httperf and was seeing a high number of connreset errors. Looking at the traffic between httperf and AOLserver 4, I see that httperf asks for HTTP 1.1 connections and tries to make more than one request per connection. However, my AOLserver is not allowing this. After sending the response to the first request, it closes the connection (FIN,ACK).
AIM [16:49] <AIM IRC Bridge> Message is too long or too complex

IRC [18:42] <cnk> OK the issue seems to mostly be how I was running the tests.
IRC [18:44] <cnk> AOLserver requires that you explicitly ask for Connection: Keep-Alive or it closes. Apache2 defaults the other way - keeps connections alive if the header doesn't say what to do.
IRC [18:44] <cnk> When I changed my httperf tests to explicitly add the header "Connection: Keep-Alive", then I got more than 1 reply per connection.
IRC [18:46] <cnk> In my AOLserver config file, I had not said anything one way or the other about keep alive or it's time out. THe AOLserver default appears to have KeepAlive on with at timeout of 30 seconds.
IRC [18:48] <cnk> I may need to set this higher because I am still getting some connreset errors - though far fewer than the 50% of requests I was getting before Dossy told me you have to ask for Keep-Alive behavior from the server.
IRC [18:49] <cnk> FWIW - Mozilla seems to automatically ask for Keep Alive, so perhaps the AOLserver behavior that confused my httperf testing isn't a big deal after all.
IRC [19:02] <|Lurch|> what size requests are you sending?
IRC [19:56] <cnk> the request sizes are small - ~71 bytes. Do you mean what size are the things I am asking to have sent back?
IRC [19:57] <cnk> if the later, then I had some small ones (21 bytes) and some normalish ones ~2kb

IRC [21:04] <|Lurch|> cnk: i was interesting in the file sizes that are being served (and your results, of course, i.e. hardware + sustained rate)
