If you're just translating one hostname to another, you can do it in DNS
with a CNAME record:

www.company1.com. IN CNAME www.company2.com.

If you also need to change the pathname component of the URL,
e.g. http://www.company1.com/XXX -> http://www.hosting.com/company1/XXX,
then you would put:

www.company1.com. IN CNAME www.hosting.com.

in your DNS, and on the www.hosting.com web server you would perform the
pathname modification in its virtual host configuration.
