Registry Information

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To use this hotfix, you must set a registry key and a string value. To do so, follow these steps:
  1. Click Start, and then click Run.
  2. In the Open box, type regedit, and then click OK.
  3. Locate the following registry key:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

  4. Right-click the Internet Settings key, point to New, and then click Key.
  5. Type PluggableProtocols.
  6. Right-click the PluggableProtocols key, point to New, and then click String Value.
  7. Type the name of the pluggable protocol that you want to enable to access cookies, and then press ENTER.

    For example, to enable the myhttp:// protocol to allow access to cookies, type myhttp. The string can have any value that you want. By default, the value is blank.
