Hello, as far as I know there are 3 ways to realize mass-hosting with apache (host to path translation):
1. mod_rewrite 2. virtualdocumentroot (mod_vhost_alias) 3. using a mod_perl-handler for URI-translation At this time I'm using the third way for my webhosting-system. But all ways have one problem: They can't set DOCUMENT_ROOT for each host, as it would have been set when the host would appear in httpd.conf as virtualhost with documentroot-directive. My idea is to write my own apache-module, that does the host to path translation and additionally set the DOCUMENT_ROOT variable. But before I start, I would like to know (because you possibly have more knowledge about the internal apache-design than me), if it is possible to set this environment-variable in this phase so it takes effect in the later content-processing. I tried to set the variable inside my mod_perl-handler, but when the script I called through http was executed, the standard-document-root appeared again. Regards Marten Lehmann
