Rewrite different page with .htaccess url rewrite - .htaccess

Question

I'd like to use .htaccess for url rewrite.
In my previous post you have shown me how to do it to the index.php page but now would like to do also for other pages like browser.error.php, etc.
To do so I tried to add the last 2 rows in the .htaccess, but unfortunately if I try the link www.mysite/browser-error/ it doesn't work - Return me in the index page.
Options +FollowSymLinks
RewriteEngine on
RewriteRule \.(css|jpe?g|gif|png|js|ico)$ - [L,NC]
# rule to ignore files and directories from all rewrite rules below
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
RewriteRule ^(.*)/(.*)/(.*)\/?$ index.php?op=$1&idric=$2&sp=$3 [L,QSA,NC]
RewriteRule ^(.*)/(.*)\/?$ index.php?op=$1&idric=$2 [L,QSA,NC]
RewriteRule ^(.*)\/?$ index.php?op=$1 [L,QSA]
#NEW ADDED ROWS
RewriteRule ^browser-error/(.*)\/?$ browser.error.php?r=$1 [L]
RewriteRule ^browser-error\/?$ browser.error.php [L]
Where I am doing wrong? How would I go? Thank you

Answer 1

I would suggest avoid use of .* and use [^/]+ instead with re-ordering of your rules:
Options +FollowSymLinks -MultiViews
RewriteEngine on
RewriteRule \.(css|jpe?g|gif|png|js|ico)$ - [L,NC]
# rule to ignore files and directories from all rewrite rules below
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
#NEW ADDED ROWS
RewriteRule ^browser-error/([^/]+)/?$ browser.error.php?r=$1 [L,QSA,NC]
RewriteRule ^browser-error/?$ browser.error.php [L,NC]
RewriteRule ^([^/]+)/([^/]+)/([^/]+)/?$ index.php?op=$1&idric=$2&sp=$3 [L,QSA]
RewriteRule ^([^/]+)/([^/]+)/?$ index.php?op=$1&idric=$2 [L,QSA]
RewriteRule ^([^/]+)/?$ index.php?op=$1 [L,QSA]

Answer 2

You have rules before preceding this rule. That makes your petition change to index.php before your rule is reached. (They all have the L flag that makes them be the LAST rule processed). As they are not restricted to not be applied when url is browser-error, they will run on every ///* or simialr petition.
Then, you should add RewriteCond to negate the browser-error url in your other RewriteRules as this:
Please try, and comment if that´s not what you need of it does not work as expected.
Hope it helps
