I would guess that the \makindex command checks to see if the compiled index file is present and opens it if that's true and, otherwise, opens the idx file for capture of the indexing commands. I assume this is needed to be done before the commands in \begin{document} are executed so there is some control over which input and output ports are used. Pure speculation on my part.

The hyperref package (you already load this) provides the \url{...} command which will be a hyperlink and also gets rid of problems with special characters, e.g., `#'. So


should do the job.
