.htaccess - Moving from IIS ISAPI rewrite to Apache mod_rewrite -

i've seen few people have asked on here already, none of solutions provided worked me far.

we have been developing iis isapi rewrite (on windows) , 1 of clients decided place project on linux server running apache. result of rules no longer working.

example of isapi rewrite rule:

rewritecond %{request_filename} !-f   rewritecond %{request_filename} !-d  rewriterule ^login/?([^/]*)([^/]*)$ /login.cfm?msg=$1&$2 [l,qsa] rewriterule ^login.cfm$  /login/ [r=301,l,nc] 

login.cfm actual existing page , not dynamically generated based on template.

could me how translate apache mod_rewrite please? rule creates infinitive loop , output is:

login/?msg=&&msg=&&msg=&&msg=&&msg=&&msg... (till limit of url length)

safe page not found either doesn't check whether file such name exists.

the page /login or /login/wrong rule should recognize both cases.

you can use these rules in site root .htaccess:

rewriteengine on  # external redirect actual url pretty 1 rewritecond %{the_request} /login\.cfm\?msg=([^\s&]*)\s [nc] rewriterule ^ /login/%1? [r=301,l,ne]  # internal forward pretty url actual 1 rewriterule ^login(?:/([\w-]+))?/?$ login.cfm?msg=$1 [l,qsa,nc]
