Redirects with Upper Case not working

Great Plugin! Have a question:

I have updated Word Press to 3.9.2 and the Safe Redirect Plugin to 1.7.3.

I checked some of my redirects and found the following:

I have versions of several redirects with a lower case and upper case version, for example:

/splitsease/afl2013
and
/splitsease/AFL2013

both redirect to the same URL:

http://www.snaplegalsoftware.com/wp-content/custom/referral.php?action=try&refer=AFL2013

In each of the cases I have checked, the lower case version works and the version with upper case gives a 404 error.

I want to have both versions since the URL’s appear in print material and I want them to be forgiving of case differences,

Any suggestions?

Thanks,

Will Binns
