We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 7.0 running on Microsoft Windows Server 2008. IIS 7.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:
When you submit an HTML form or click a link to a script from the webbrowser, you may receive an error similar to the following:
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:
Can't open perl script "c:\inetsrv\wwwroot\scripts\test.pl": No such file or directory
This error is caused by missing or malformed CGI header information. Inthis case the headers are missing because the script file could not be run,resulting in that error message being displayed instead of the output fromthe script.
The Common Gateway Interface (CGI) Specification calls for the script fileto return at least one header. These headers fill out the remainder of theHTTP headers as required by the HTTP protocol. The HTTP protocol alsorequires a blank line between the end of the headers and the start of thedocument. The only headers currently supported by the CGI specificationare:
Content-type: Location: STATUS
Additional information about these headers can be found in the HTTPProtocol and CGI Protocol draft specifications available athttp://www.w3.org.
