Hi, I came across a strange behavior of mod_rewrite while using with zope. Although it is not a zope question, I was wondering if any of you have run into this. We are using mod_rewrite to redirect the users to one of the zope sites of a Zeo cluster.
The directive RewriteMap has unexpected behavior when it is used to define more than one map with same map name in diffrent places. Normally all the directives within a tag applies only to that tag. For example: <VirtualHost *> ServerName www.foo.com DocumentRoot /var/www/foo RewriteEngine on RewriteLog /var/log/httpd/foo.log RewriteLogLevel 2 RewriteMap map rnd:/etc/httpd/conf/foomap.txt RewriteRule ^/Foo(.*) http://127.0.0.1${map:IP}/VirtualHostBase/http/foo/$1 [L,P] </VirtualHost> <VirtualHost *> ServerName www.bar.com DocumentRoot /var/www/bar RewriteEngine on RewriteLog /var/log/httpd/bar.log RewriteLogLevel 2 RewriteMap map rnd:/etc/httpd/conf/barmap.txt RewriteRule ^/Bar(.*) http://127.0.0.1${map:IP}/VirtualHostBase/http/bar/$1 [L,P] </VirtualHost> The above is expected to work. However ModRewrite, does not read the map file foomap.txt or barmap.txt everytime it needs it and it caches the results after the first time it reads for faster operation. The problem is the cache treats both the file as the same since they have the same name! Hence if you visit foo.com first, the data stored in foomap.txt is returned from the cache next time you visit foo.com or bar.com. This causes apache to redirect into the wrong zope site. Has anyone else experienced similar problems ? thanks, ganesh Zeomega LLC Open minds' Open Solutions Plano, Texas, USA Bangalore, India phone: 972-731-6750 http://www.zeomega.com _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
