URI Case Sensitivity

In case you ever run into a problem where you are wondering if urls are case sensitive or not here is a couple things you’ll want to keep in mind. First the host and scheme are NOT case sensitive. This means the following list are all valid.

hTtP://benFalk.CoM/index

http://benfalk.com/index

HTTP://BenFalk.COM/index

After the host all non-encoded characters are considered to be case sensitive. This means that if you decide to treat all of the following as the same route you may want to redirect the requests preferably to the lower case version.

http://benfalk.com/Index

http://benfalk.com/index

http://benfalk.com/INDEX

If you have encoded characters, those are not case sensitive. To explain, if you see a url that looks like this:

http://benfalk.com/is übber

It will be encoded into the following by the browser:

http://benfalk.com/is%20%G%C3%BCbber

 
%20 = (space)

%G%C3%BC = ü

These “percent encoded” characters are not case sensitive, so these are to be considered equal.

%G%C3%BC

%g%c3%bc
