Redirect php query with hash using htaccess regex

Question

I'm trying to redirect URLs with a half of MD5 part inside a PHP query and one base64 encoded string after a '#' symbol to a new directory using a .htaccess Rewrite Rule.

URL examples:

A) /?7027fcbbc2a1ccb9#N61/vMSRNqYQBhb+DcaSfv2YGW1HiBbSpMUoSHrtxok=

B) /index.php?f9c4bb60426abaf9#RBmcvFnf5+wFwP54IM8f7pUSvmPn2aOFm1Z6LbIOFK8=

The URL contains two parts:

A half MD5 hash (16 a-f and 0-9 hash)
Followed with one "#" then a base64 encoded string

I'm trying to ask if the URL containts the 16 alphanumeric chars, and if yes, I want to redirect the whole URL (including the #hash followed info) to a new directory.

I'm trying with this Rule:

RewriteRule ^\\?[a-f0-9]{16}$ /newdirectory/$1 [L]

But of course it doesn't work. What is the correct regex for the redirection? Thank you so much!

@anubhava Something like this: http://example.com/?7027fcbbc2a1ccb9#N61/vMSRNqYQBhb+DcaSfv2YGW1HiBbSpMUoSHrtxok= and i want redirect to: http://example.com/newdir/?7027fcbbc2a1ccb9#N61/vMSRNqYQBhb+DcaSfv2YGW1HiBbSpMUoSHrtxok= Regards! — Vega

What you have in your URL is actually a query string not request URI. You can use this rule in your site root .htaccess:

RewriteEngine On

RewriteCond %{QUERY_STRING} ^[a-f0-9]{16}$ [NC]
RewriteRule ^/?$ /newdir/ [L,R=301,NE]
