I've got a domain, allows say world wide web.mycompany.com.

Can you really redirect world wide web.mycompany.com to world wide web.domain.com#mycompany rather through my domain provider?

Theoretically, Your domain provider provides DNS servers that only resolve your domains into IP addresses. After that it can be the clients/browsers to transmit the asked for domain title or Hyperlink to among the IP addresses. So usually your domain provider cannot redirect your domain title to a different URL. But it is recommended to seek advice from your domain provider, they may provide HTTP servers to redirect the demands. Otherwise, you need to redirect it using your own HTTP server.

If you're able to put an internet page at world wide web.mycompany.com/index.html, put this within the content:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4. Transitional//EN">

<html>

<head>

<title>Your Page Title</title>

<meta http-equiv="REFRESH" content="0url=http://world wide web.domain.com#mycompany">

As Innerpeacer stated, you will never redirect a website title to some hashed URL without dealing with an internet page (or cgi) redirect.
