Auto transform to lower-case

hi all

We put with linkit a external url like this http://www.data.com/2016-12-03_STDamen.pdf
Linkit transform the URL to lower case (also to http://www.data.com/2016-12-03_stdamen.pdf).
So after the transformation the URL is not working, because the external server don't find this url with lower case.

Can you prevent the transformation to lower case? I mean that the URL must be how they is tap in.

Thank you for your hep
