Why redirect to home? Where is the mistake?

Question

Joomla

There is a path mysite.ru/news?limitstart=0
need to get rid of ?limitstart=0
I try:

RewriteCond %{QUERY_STRING} ^limitstart=0$
RewriteRule ^news http://mysite.ru/news? [R=301,L]

But it redirects to home page instead of /news

Answer 1

Got this option

RewriteCond %{QUERY_STRING} (^|&)limitstart=0($|&)
RewriteRule ^news$ /news? [L,R=301]

Answer 2

RewriteCond %{QUERY_STRING} ^limitstart=0$
#если гет запрос
RewriteCond %{REQUEST_URI}  ^news=0$
# И ньюс
RewriteRule ^.* http://mysite.ru/news? [R=301,L]

Otherwise you have a cycle
