how to Rewrite Single Page url in .htaccess - .htaccess

Question

I need to rewrite only 1 specific URL
from
http://www.domainname.com/index.php?route=payment/axis/callback
to
http://www.domainname.com/payment/axis/callback
I tried these two from stack overflow, I don't know why its not working
1st one :
RewriteRule ^([A-Za-z0-9-]+)/?$ index.php?route=payment/axis/callback [NC,L]
2nd one :
RewriteRule ^index.php?route=payment/axis/callback payment/axis/callback [L]

Answer 1

Try this:
4) Rewriting yoursite.com/user.php?username=xyz to yoursite.com/xyz
Have you checked zorpia.com.If you type http://zorpia.com/roshanbh233 in browser you can see my profile over there. If you want to do the same kind of redirection i.e http://yoursite.com/xyz to http://yoursite.com/user.php?username=xyz then you can add the following code to the .htaccess file.
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1
See the full page here.
Hope it helps!

Answer 2

I wouldn't use .htaccess with RewriteRule, since there are often problems with it. A simple workaround (with PHP redirect):
<?php
if($_GET['route'] == 'payment/axis/callback') {
header("Location: http://www.domainname.com/payment/axis/callback");
}
?>

You can either use h0ch5tr4355's workaround or you can try this:
RewriteEngine on
RewriteCond %{QUERY_STRING} ^route=payment/axis/callback$
RewriteCond %{SCRIPT_FILENAME} index.php
RewriteRule (.*) /payment/axis/callback [NC,QSD]
If you instead of a rewrite would like it to redirect to the new url you can add R=301 to the flags of the RewriteRule.
