How does one insert a URL correctly?
I'm writing up a document, and at one point I cite a file online found at http://www.math.uconn.edu/~kconrad/blurbs/grouptheory/groupsp3.pdf
I made a footnote with
\footnote{http://www.math.uconn.edu/\textasciitilde kconrad/blurbs/grouptheory/groupsp3.pdf}
I had to find an alternative for the ~ since it would not show up in the final document. This works fine when copy+pasting to a web browser, but is it possible to just link to the page from the pdf by clicking on the footnote?
P.S. If there's a better fix to the ~ issue, I'd be glad to see that as well.
