** answer **

thanks howlin

rewriteengine on  rewritecond %{the_request} ^(get|post)\ /project/profile\.php\?user=(.*)\ http rewriterule ^ /project/%2\? [r=301,l]  rewritecond %{query_string} !user= rewriterule ^(.*)$ /project/profile.php?user=$1 [l] 

this should work:

rewriteengine on rewritecond %{the_request} ^(get|post)\ /project/profile\.php\?user=(.*)\ http rewriterule ^ /project/%2\? [r=301,l]  rewritecond %{query_string} !user= rewriterule ^project/(.*)$ /project/profile.php?user=$1 [l] 

the above change project/profile.php?user=username project/username , load information project/profile.php?user=username page

edit:

rewriteengine on  rewritecond %{the_request} ^(get|post)\ /project/profile\.php\?user=(.*)\ http rewriterule ^ /project/%2\? [r=301,l]  rewritecond %{query_string} !user= rewritecond %{request_filename} !-d   rewritecond %{request_filename} !-f   rewriterule ^(.*)$ /project/profile.php?user=$1 [l]
