Resin's load balancer (proxy) is an entire different module from Resin's basic HTTP processing. Load balancing is a far more complicated issue than HTTP protocol parsing, because the load balancer handles another set of sockets/round-robin, etc. HTTP is just parsing strings.
The issue in 4.0.2 was the load-balancer to Resin communication protocol (basically messed-up acks). It had nothing at all to do with HTTP. -- Scott > > jon > > > On Sat, Jan 16, 2010 at 10:02 AM, Scott Hernandez > <[email protected] <mailto:[email protected]>> wrote: > > It depends on what your services, performance, and bandwidth > requirements are. > > Anyway, there are (a few) options. > ldirectord - (low level) http://linux.die.net/man/8/ldirectord > balance -- (low level) http://www.inlab.de/balance.html > trafficmanager -- (yahoo lb turned open-source) > http://incubator.apache.org/projects/trafficserver.html > zxtm -- (free/commercial) > http://www.zeus.com/products/traffic-manager/index.html > > You can do this at the network level (MAC/IP) or application level > (http, etc.). > > There are tons of reverse-proxies with load-balancing too. > > There is nothing wrong with using Apache and Resin, but people do use > apache for things that aren't in its core set of features and then > wonder why there are problems... > > On Sat, Jan 16, 2010 at 2:24 AM, Wesley Wu <[email protected] > <mailto:[email protected]>> wrote: > > Hi Jon & Scott, > > > > I don't like apache either but resin 4.0.2 cluster web-tier seems > > unstable for me. > > > > I've not tested the 4.0.3 cluster. > > > > My Apache config: > > > > ResinHost 192.168.1.4 6801 > > ResinBackup 192.168.1.5 6801 > > > > Which load balancer will be more appropriate for this usage? > > Thanks. > > > _______________________________________________ > resin-interest mailing list > [email protected] <mailto:[email protected]> > http://maillist.caucho.com/mailman/listinfo/resin-interest > > > ------------------------------------------------------------------------ > > _______________________________________________ > resin-interest mailing list > [email protected] > http://maillist.caucho.com/mailman/listinfo/resin-interest > _______________________________________________ resin-interest mailing list [email protected] http://maillist.caucho.com/mailman/listinfo/resin-interest
