regex - htaccess rule delimiters and params for smooth urls -

i'm trying use htaccess rewrite rules create smooth urls. user can call example http://members.clubseat.at/demo/login/?test=123 , code user called http://members.clubseat.at/demo/index.php?page=login&test=123.

here htaccess code:

rewriteengine on  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d  rewriterule ^([^/]*/)?([^/]*)/?$ ./index.php?p1=$1&p2=$2 [qsa,l] 

i want user can leave additional params after page , last slash, .../demo/login/ , .../demo/login work. if there no last slash (/) login not in first param in second.

compare: http://members.clubseat.at/demo/login/ vs. http://members.clubseat.at/demo/login

try demo here: http://members.clubseat.at/demo/login/?test=123

but according regex-tester should work: https://regex101.com/r/nk9rm2/2

how can solve problem?

you need use qsa flag append query strings target url.

rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d  rewriterule ^([^/]*)?/?([^/]*)/?$ ./index.php?p1=$1&p2=$2 [qsa,l] 

the third perm automatically appended qsa flag.
