Assigning substyle to language

[lapinkulta]

Hi!

I am running a forum in three languages. The language is selected automatically from the used subdomain. I have "created" a plugin for that reason. Now i wanted that forum titles and descriptions are replaced with the help of replacement variables in each substyle. I haven't found another way to bind languages to styles, so here is how the code of the plugin looks:

if ($_SERVER['HTTP_HOST'] == "en.domain.com") {
				$_REQUEST['langid'] = 3;
				$_REQUEST['styleid'] = 4;
		} elseif ($_SERVER['HTTP_HOST'] == "de.domain.com") {
				$_REQUEST['langid'] = 2;
				$_REQUEST['styleid'] = 3;
		} else {
				$_REQUEST['langid'] = 16;
				$_REQUEST['styleid'] = 5;
		}

I use the hook "init_startup" without having an idea about the hook system. Anyway it worked with the language selection.

problem a.)
Now the replacement variables only work when user is logged in! When user is browsing as guest variables are not replaced. Maybe wrong hook?

problem b.)
Another problem is vbseo which i use. Even user is logged in (and title/description) is replaced correctly, the path still points to the variable like domain.com/forum/title1 instead of domain.com/forum/animals

Thanks for your help.
