Create a link that shows a specific topic and the TOC

How do you create a link to a specific topic and also show the TOC?

I thought I just had to include a little number sign, like this:

http://samplewebpath/acmeapplication/webhelp/index.htm#contact.htm (with TOC)

http://samplewebpath/acmeapplication/webhelp/contact.htm (No TOC)

But this doesn't work at all. Using RH 7.
