How to create my own URL-handler

Question

I have two links:

1. http:\one
2. UB:\two

Default browser is IE. In need that second URL was opened in Chrome browser.

I did this:

1. Created and launched reg file which contains:

   Windows Registry Editor Version 5.00
   
   [HKEY_CLASSES_ROOT\docnet]
   @="URL:UB Protocol"
   "URL Protocol"=""
   
   [HKEY_CLASSES_ROOT\docnet\shell]
   @=""
   
   [HKEY_CLASSES_ROOT\docnet\shell\open]
   
   [HKEY_CLASSES_ROOT\docnet\shell\open\command]
   @="C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe %1"
   
   [HKEY_CLASSES_ROOT\ub]
   @="URL:UB Protocol"
   "URL Protocol"=""
   
   [HKEY_CLASSES_ROOT\ub\shell]
   @=""
   
   [HKEY_CLASSES_ROOT\ub\shell\open]
   
   [HKEY_CLASSES_ROOT\ub\shell\open\command]
   @="C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe %1"
   

2. Created link "ub:\two" in Outlook and clicked on it.

3. Profit, but it opens only Chrome browser without going through link. Just empty browser, as i would open it by shortcut.

How can i make browser to go by link?

I've seen similar question here but i found no answer.
