Administering an ISP Installation

Disabling Socket Pooling

IIS 5.0 sites that are bound to different IP addresses—but the same port number—share the same set of sockets. This feature allows more sites bound to an IP address to be created on the same machine than was possible in IIS 4.0. In IIS 5.0, these sockets are used flexibly among all of the sites, in order to reduce resource consumption.

Socket pooling is now the default for IIS 5.0, and in general, you don’t need to change it. However, both bandwidth throttling and performance adjustments will apply to all Web sites configured for the same port. So, if you intend to enable bandwidth throttling or do performance tuning on a per-site basis, you will need to disable socket pooling.

To disable socket pooling, type the following at the command prompt:

c:\inetpub\adminscripts\cscript adsutil.vbs set w3svc\disablesocketpooling true

The command prompt will reply:

disablesocketpooling : (BOOLEAN) True
