Disable POST processing

Hi,
i’ve a high load wordpress instance, and it seems the pretty link functions are even triggered for POST requests (e.g. /wp-admin/admin-ajax.php), which increases MySQL load.

So with hundreds of parallel users every ajax call is resulting in additional pretty-link-calls on the database.

It would be greate to have a filter hook to disable processing of POST requests at all, if only pretty link functions are used without any advanced tracking.

I just added the following snippet in the function prli_redirect() in the file prli-main.php to disable processing of POST requests:

if($_SERVER["REQUEST_METHOD"] != 'GET')
    return;

Here are some Samples of the calls BEFORE this change:

443354 Query  select blockedTime, reason from wpexample_wfBlocks where IP='xxx' and (permanent=1 OR (blockedTime + '300' > unix_timestamp()))
