I have the following regular expression used for pattern matching in a URL rewrite in IIS that was set up by my predecessor:
^$
I know very little regex, and the reading I've done this morning hasn't helped me in figuring out how this one works.
It is rewriting:
http://dittest/
to:
http://dittest:8080/dit
Why does the ^$ regex work in testing the URL http://dittest/ and rewriting to http://dittest:8080/dit if ^$ is supposed to match an empty string?
This question is not a duplicate, because it's not asking what the regex means – rather why it works in using it for an inbound rule URL rewrite in IIS when it doesn't work to validate http://dittest/.
I appreciate the help. Thank you!
