Click Start, click Run, type %systemroot%\system32\inetsrv\iis.msc, and then click OK.
Expand the computer name that you want to configure.
Right-click the Web site that you want to configure, and then click Properties.
On the Home Directory tab, click Configuration.
Click to select the Cache ISAPI applications check box.
Click OK two times.
