Troubleshooting CGI Error

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:

Symptoms

When you submit an HTML form or click a link to a script from the web browser, you may receive an error similar to the following:

CGI Error


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

↑ Back to the top

Cause

This error is caused by missing or malformed CGI header information. In this case the headers are missing because the script file could not be run, resulting in that error message being displayed instead of the output from the script.

More Information

The Common Gateway Interface (CGI) Specification calls for the script file to return at least one header. These headers fill out the remainder of the HTTP headers as required by the HTTP protocol. The HTTP protocol also requires a blank line between the end of the headers and the start of the document. The only headers currently supported by the CGI specification are:


   Content-type:
   Location:
   STATUS


Additional information about these headers can be found in the HTTP Protocol and CGI Protocol draft specifications available at
http://www.w3.org.
