I honestly just recommend using example.com/username or example.com/users/name

I need to develop a website - where users would have their page of details (users?m=details...) as subdomain of main domain. So, it will look like a small website.

thank you for details ))) it is interesting, that in #3 you're placing index.php in the end. I wasn't thinking about this.

I understand that urltrans is not enough, but I do not neet to rewrite SPECIFIC user - I need a mask for all users, but don't know how to setup VirtualHost and .htaccess to work with this urltrans we created...

Would you give more advice?

To be cleared… You can not «drive» this system for full without modifying «.htaccess». It's a two-ends system - one part is defined with «urltrans.dat» that force CMS to automatic (with cot_url function) translate URL to «magic» format you need. Second part is .htaccess that takes site user coming with «magic» URL to a CMS real address.

So, if you need user get profile details by accessing URL like http://username.yousite.com/  you must check this steps (actual for Siena version):

1. install «URL Editor» plugin
2. select «Custon urltrans.dat» in settings of «URL Editor»
3. Make rule in Admin page of «URL Editor», like this:
     users         m=details&u=*     http://{$u}.{$_rhost}{$_path}index.php

Now you will get URL like:  http://admin.site.com/index.php?m=details    with executing cot_url('users','m=details&u=admin') some where on site.

4. Make changes in .htaccess to propper «translate» http://admin.site.com/index.php?m=details in normal  http://site.com/users.php?&m=details&u=admin

I hope it is possible to tweak it without editing .htaccess.

So, I try this in urltrans.dat:

users	m=details&u=*			{cot_url_username()}.{$_host}

and this

users	m=details&u=*			http://{cot_url_username()}.{$_host}

in first case link is relative to domain. In second case, it didn't work.

Please, help with this!
