Description

If a user calls a not existing website on my server my application generates a custom error page. But this is not possible, if the uri string contains % + special character, e.g. https://yandex.ru/%?

Resolution: invalid
Status: newclosed

The % character is only valid in URI if followed by two hexadecimal digits, anything else is a violation of HTTP protocol and will result in 400 Bad Request being returned.
