RE: Mod_jk log message question (mod_jk is so slow!!!)
Does anyone at all know of any way to optimize the speed of sending requests to tomcat from apache? I have turned off all logging, which has helped a bunch, is there anything else I can do? The biggest problem is that all static resources (.gif, .html, etc.) get sent to Tomcat if they are inside a webapp. How do you get around this on tomcat 3.2.4? Can I force apache to serve up the images even if they are inside a webapp? Would mod_webapp solve my problem? Please Help!

RE: Mod_jk log message question (mod_jk is so slow!!!)
Pascal, Thanks for the response! That document is extremely helpful!!! I have actually seen that before and considered implementing load balancing for other reasons, but are you suggesting that load balancing will fix my problem? It seems that if a single page inside of a webapp has many images on it, apache will still send the static files to one of the tomcat servers via ajp13, which will still be slow. The difference between Apache serving the file directly and Apache redirecting the page to tomcat is about 3 seconds vs. 30 seconds...

RE: Mod_jk log message question (mod_jk is so slow!!!)
in the JKMount directive which is present in your mod_jk.conf.auto file generated by TC or in your httpd.conf of Apache if you wrote it yourself, you must declare only the servlets and the jsp files. it should be something like : JkMount /your_webapp/*.jsp ajp13 JkMount /your_webapp/servlet/* ajp13 With this configuration, Apache serves itself all the static ressources (HTML, images, ...) arno# -Message d'origine- De: Brandon Cruz [SMTP:[EMAIL PROTECTED]] Date: jeudi 18 avril 2002 16:23 A: Tomcat Users List Objet: RE: Mod_jk log message question (mod_jk is so slow!!!)

RE: Mod_jk log message question (mod_jk is so slow!!!)
I tried to tweak everything I possibly can. mod_jk works the same way as mod_webapp then right? For example, every single request for something that lies under /myWebapp/* gets redirected to tomcat, not just the *.jsp files and /servlet/*. Any way to change this besides what I have done? -Original Message- From: Ralph Einfeldt [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 18, 2002 10:35 AM To: Tomcat Users List Subject: AW: Mod_jk log message question (mod_jk is so slow!!!) As I see it, something must be wrong with your setup. AFAIK mod_jk doesn't send any request to tomcat that doesn't match the JkMount expressions. The current version of mod_webapp is directing all resources under a webapp to tomcat. So it won't help you. -Ursprüngliche Nachricht- Von: Brandon Cruz [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 18.

Yes!!! That's exactly what I was looking for!!! I didn't realize that you can put a wildcard in the middle of the declaration.

Re: Mod_jk log message question (mod_jk is so slow!!!)
but are you suggesting that load balancing will fix my problem? No, I meant that the setup described in my document has the JKMount directives configured to serve static content from Apache and sent *.jsp and servlet requests to tomcat.
