WebObjects uses a variety of different HTTP adaptors to enable access to applications through the Web server. Depending on your deployment platform, particular HTTP adaptors are installed by default. Table 3-2 lists the supported adaptors that are installed on each platform.
| Apache | ISAPI | NSAPI | CGI | |
| Mac OS X Server | version 1.3.14 | x | ||
| Solaris | version 1.3.9 | version 6.0 SP2 | x | |
| Windows 2000 | version 5.0 | x |
In Mac OS X Server and Solaris, the Apache adaptor is active by default. Requests in the form http://.../cgi-bin/WebObjects/ are handled by the Apache adaptor. If you disable the Apache module, then such requests are handled by the CGI adaptor. In Windows 2000 the ISAPI adaptor is the default.
