DOCUMENT:Q150835 12-DEC-1999 [iis] TITLE :Troubleshooting CGI Error PRODUCT :Internet Information Server PROD/VER:winnt:1.0 OPER/SYS: KEYWORDS:kbsetup ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Server 1.0 ------------------------------------------------------------------------------- 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 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.
