400 Bad Request when URL ends with %

Question

All the URLs ending with % is giving following error

"Bad Request,Your browser sent a request that this server could not understand."

I have redesigned my website and earlier as per my google analytics URLs ending with % was running.

I want to mention that I tried using same old htaccess but was not able to fix it. Other important change which I made was in hosting where I have pointed my server into a sub folder or the root.

Please help me in fixing it

Answer 1

% is a reserved character and should not be used for anything except percent encoding.

If you really need to pass the character on your url, use %25

Answer 2

Try this: 400 Bad Request when URL ends with % (move your mouse over it and look at the URL, it's the URL of this page with a % added to it!)

The problem is probably that the % is used as an escape character for special signs like spaces or non latin characters, and the browser expects a code behind it.
