Do not use underscores in DNS computer names

The support of Internet Explorer with underscore is not the same as for browsers like firefox and chrome.

Take the following address: http://pc02_test.domain.com/webapp

When you now want to store some information in the cookie, this goes wrong. So the advise is do not use underscores!

  1. A hyphen is also better for your Google score. Underscores are ignored and hyphens are treated as word separators.

  2. @mqaa: you are completly correct. But the problem with the underscore in the DNS name is that the cookie information is not stored in Internet Explorer.
