Re: Virtual host with Squid, Apache and Tomcat
Hi, As far as I know, we can do it in both workers2.properties and httpd.conf (virtual hosts). It seems some problem in apache side virtual host configuration for the same uri for example VirtualHost ServerName www.abc.com DocumentRoot Location /eng/* JkUriSet worker channel.socket:192.168.1.10:8008 JkUriSet vhost www.abc.com JkUriSet context /eng /Location Location /fre/* JkUriSet worker channel.socket:192.168.1.10:8009 JkUriSet vhost www.abc.com JkUriSet context /fre /Location /VirtualHost VirtualHost ServerName www.xyz.com DocumentRoot Location /eng/* JkUriSet worker channel.socket:192.168.1.11:8008 JkUriSet vhost www.xyz.com JkUriSet context /eng /Location Location /fre/* JkUriSet worker channel.socket:192.168.1.11:8009 JkUriSet vhost www.xyz.com JkUriSet context /fre /Location /VirtualHost [uri:www.xyz.com/eng/*] info=eng web app context=/ group=lb-gipalbum debug=0 www.abc.com virtual host pattern will be overwritten by www.xyz.com virtual host pattern. You can find it in jkstatus page. Always you will be redirected to 192.168.1.11 tomcats. Please let me know if you can find the solution. To fix the above problem you can use workers2.properties as follows [channel.socket:192.168.1.10:8008] info=Ajp13 forwarding over socket to 10-8008 tomcat tomcatId=abc_eng lb_factor=1 debug=0 [channel.socket:192.168.1.10:8009] info=Ajp13 forwarding over socket to 10-8009 tomcat tomcatId=abc_fre lb_factor=1 debug=0 [channel.socket:192.168.1.11:8008] info=Ajp13 forwarding over socket to 11-8008 tomcat tomcatId=xyz_eng lb_factor=1 debug=0 [channel.socket:192.168.1.11:8009] info=Ajp13 forwarding over socket to 11-8009 tomcat tomcatId=xyz_fre lb_factor=1 debug=0 [uri:www.abc.com/eng/*] info=ABC Eng context=/eng group=abc_eng debug=0 [uri:www.abc.com/fre/*] info=ABC Fre context=/eng group=abc_fre debug=0 [uri:www.xyz.com/eng/*] info=XYZ Eng context=/eng group=xyz_eng debug=0 [uri:www.xyz.com/fre/*] info=XYZ Fre context=/eng group=xyz_fre debug=0 At 04:25 PM 11/21/2003 +0100, you wrote: Hi I'm new to the list, so... hi! :-) Here's our scenario: We use Squid as a reverse proxy cache in front of Apache which in return calls Tomcat for dynamic content: Browser -- Squid -- Apache -- Tomcat Until now we used the old mod_webapp, but now we're changing to mod_jk2 (with Apache 1.3 and Tomcat 4.1). We need to have several hosts on the same Apache and thus use virtual hosts. The problem is that the web applications sometimes need to have the same name. An example: www.abc.com has two web applications, one for each language (ISO codes): www.abc.com/eng/ and www.abc.com/fre/ (French) www.def.com also has two web applications which are different, but have the same name: www.def.com/eng/ and www.def.com/fre/ Now, with the old mod_webapp, all we had to do is define a unique name for each of those (we chose a three-letter acronmy of the site plus the web application name), in this case abc_eng, abc_fre, def_eng and def_fre and point to them in the virtual host definition of Apache, like this: VirtualHost ServerName www.abc.com DocumentRoot WebAppDeploy abc_eng /eng WebAppDeploy abc_fre /fre /VirtualHost VirtualHost ServerName www.def.com DocumentRoot WebAppDeploy def_eng /eng WebAppDeploy def_fre /fre /VirtualHost As far as I can see, with mod_jk2, this is not possible in Apache alone. Am I right? I read on a couple of pages how Tomcat can be configured for virtual hosting, but I think these examples were all assuming that you use Tomcat as the web server. From what I understand I would need to define something like this in server.xml: Host name=www.abc.com debug=0 appBase=webapps unpackWARs=true Context path=/eng docBase=abc_eng debug=0 reloadable=true/ Context path=/fre docBase=abc_fre debug=0 reloadable=true/ /Host Host name=www.def.com debug=0 appBase=webapps unpackWARs=true Context path=/eng docBase=def_eng debug=0 reloadable=true/ Context path=/fre docBase=def_fre debug=0 reloadable=true/ /Host Another problem which may arise is that the domain names point to Squid, thus Apache only responds to the IP address. Frankly, I don't know exactly how Apache does the DNS lookup, and I know there's a parameter in the server.xml that enables DNS lookups. Surely, this is necessary for this scenario to work? Anyway, in a nutshell: Has anybody ever done this? Will this work? Any help is greatly appreciated!

Virtual host with Squid, Apache and Tomcat
Hi I'm new to the list, so... hi! :-) Here's our scenario: We use Squid as a reverse proxy cache in front of Apache which in return calls Tomcat for dynamic content: Browser -- Squid -- Apache -- Tomcat Until now we used the old mod_webapp, but now we're changing to mod_jk2 (with Apache 1.3 and Tomcat 4.1).
