RewriteRule, can't make it work

Question

URL: http://mysite.com/amember/login.php?amember_redirect_url=/ajax/?id=9999

I need it to be rewritten to: http://mysite.com/amember/login.php?amember_redirect_url=/?p=9999

I mean all of the urls of that type (with ID on the end) My rewriterule:

RewriteRule http://mysite.com/amember/login.php\?amember_redirect_url=/ajax/\?id=(.*) http://mysite.com/amember/login.php\?amember_redirect_url=\/?p=$1 [R=301,L]

So far looks legit, but it doesn't seem to be working...

Before that line I have 3 following lines:

RewriteEngine on
RewriteBase /
RewriteRule ^members/(.*) http://mysite.com/$1 [R=301,L]

Update. Tried this:

RewriteRule /amember/login.php\?amember_redirect_url=/ajax/\?id=(\d+) /amember/login.php?amember_redirect_url=/?p=$1 [R=301,L]

doesn't work

RewriteRule ^amember/login.php\?amember_redirect_url=/ajax/\?id=(\d+) /amember/login.php?amember_redirect_url=/?p=$1 [R=301,L]

either

RewriteRule ^amember/login.php\?amember_redirect_url=/ajax/\?id=(\d+) http://mysite.com/amember/login.php?amember_redirect_url=/?p=$1 [R=301,L]

either

UPDATED:

RewriteCond %{QUERY_STRING} ^id=(.*)$ [NC]
RewriteRule /amember/login.php\?amember_redirect_url=/ajax/$ /amember/login.php\?amember_redirect_url=/?p=%1 [NC,R=301,L]

You can't match against the query string in a RewriteRule. If you are requesting http://localhost/amember/login.php?something&foo, the URI passed to a RewriteRule is only /amember/logi.php, therefore anything with a \? will not match unless there's an encoded ? (via a %3F) in the URI.

Additionally, you have a single param in your query string:

amember_redirect_url = /ajax/?p=9999

The ? inside the query string parameter's value isn't a parameter by itself because it's not separated by a &, so you need to match against that and rewrite that:

RewriteCond %{QUERY_STRING} (.*)amember_redirect_url=/ajax/(.*)
RewriteRule ^/?amember/login\.php$ /amember/login.php?%1amember_redirect_url=/%2 [L,R=301]
