My htaccess rule is :
RewriteCond %{QUERY_STRING} ^param1=val1
RewriteRule ^index\.php$ /page1 [L,R=301]
This redirects to the url : http://myhost/page1?param1=val1
If my url is : http://myhost/index.php?param1=val1¶m2=val2
should redirects to : http://myhost/page1?param2=val2
That means, it should not include the matched query string in RewriteCond
Just use a group matching:
RewriteCond %{QUERY_STRING} ^param1=val1(?:&(.+))?$
RewriteRule ^index\.php$ /page1?%1 [R=301,L,NC]
^param1=val1(?:&(.+))?$ without the &.
http://myhost/index.php?param1=val1¶m2=val2 should redirects to : http://myhost/page1?param2=val2. This is working fine. But if I has the url : http://myhost/index.php?param1=val1 then it is getting redirected to http://myhost/page1?%1 I want to get rid of that ?%1 part if it does not has the parameters
B flag with the R=301 one. If that doesn't help, you'd have to break the rules into two separate ones.B flag. So I have achieved that with 2 rules.. Thanks for your helpYou can use:
RewriteCond %{QUERY_STRING} .*&?(param\d=val\d)
RewriteRule ^index\.php$ /page1?%1 [R=301,L,NC]
With:
http://myhost/index.php?param1=val1 -> http://myhost/page1?param1=val1
and
http://myhost/index.php?param1=val1¶m2=val2 -> http://myhost/page1?param2=val2
But only if the real name is param1, param2, param3...
