Maybe you know if I can do this.
I want the urticaria rule to be hives. But the hiv-aids rule always catches it. And even it will not let me use hives-treatment.php for the filename.
RewriteRule ^urticaria[a-z_\-\./]*$ urticaria-treatment.php
RewriteRule ^hiv|aids[a-z_\-\./]*$ hiv-aids-treatment.php
So this rule goes to hiv-aids:
RewriteRule ^urticaria[a-z_\-\./]*$ hives-treatment.php
But if it can't be done it's not the end of the world.
And what I really want is this rule to go to hives but even the above rule would be better than that filename urticaria.
RewriteRule ^hives[a-z_\-\./]*$ hives-treatment.php
Maybe there is a way to tell the hiv-aids rule to ignore (hive).
Also, my code shows the url ending with hiv-aids-treatment.php, so I can't disallow letter 'e'.
