Question

htaccess

Worked great on old hosting
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(.+)\.dssaw\.ru$ [NC]
RewriteCond %{HTTP_HOST} !^www\.dssaw\.ru$ [NC]
RewriteCond %{REQUEST_URI} !^/sub
RewriteRule ^(.*) %{HTTP_HOST}$1
RewriteRule ^(.*)\.dssaw\.ru(.*) /sub/
RewriteRule ^sub\.(.*) /sub/
on new
"Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace."
I can’t understand what’s wrong, the essence of the script is simple, if there is no subdomain, we display what is in the sub/ folder of the main domain, in
total, turning to
dom.site.ru,
we display what is here
home/site.ru/sub
, that is, we don’t redirect somewhere, namely, we display the total people see it seems like a normal site dom.site.ru
pie.gg55.ru here is the same script on another hosting, in fact there is no subdomain pie and a redirect it seems like there is none, content is simply loaded from the sub folder of the main domain

Answer 1

Doesn't this bullshit bother you? RewriteRule ^(.*) %{HTTP_HOST}$1

10
20 GOTO 10

and by the way, this one? RewriteRule ^(.*)\.dssaw\.ru(.*)/sub/
Why don't you have any redirect status?
