Hi all,

I am exporting an org file to html with a table of contents.  In the file,
some subheadings are/have URLs.  There are not shown in the ToC in the
exported HTML page -- as if they are blank.  Exporting to latex yields no
such issues.

What's wrong?  Reading the manual I didn't find an option that toggles this
behavior.

Thanks,
Zongheng
