Question:
How to make a redirect from pages with a slash to without?
Currently using:
RewriteCond %{REQUEST_URI} !\?
RewriteCond %{REQUEST_URI} !\&
RewriteCond %{REQUEST_URI} !\=
RewriteCond %{REQUEST_URI} !\.
RewriteCond %{REQUEST_URI} !\/$
RewriteRule ^(.*[^\/])$ /$1/ [R=301,L]

Answer 1

get is not part of the url, {REQUEST_URI} is not corny to it.

# 301 --- http://www.mydefile.ru/company/?section=torgovlya&PAGEN_1=9 => http://www.mydefile.ru/about/
RewriteCond %{QUERY_STRING} (^|&)section=torgovlya($|&)
RewriteCond %{QUERY_STRING} (^|&)PAGEN_1=9($|&)
RewriteRule ^company/$ /about/? [L,R=301]

Pay attention to ?at the end of the rewrite rule, it will remove the get itself.
Also, if you need to redirect TO a page with GET, do not forget to escape it
