Appendix E: APPX Environment Variables
Debugging - APPX CGI Interface Variables
APPX_CGIDATA_LOG
Specifies the log file name into which CGI data parsing debug information is written. If you are running APPX using the CGI interface, and want to see exactly what variables are being received by the APPX process during the CGI data import, set this variable to the name of a valid log file. The CGI data parsing routine will record the variables and values it finds on its input stream in the designated file.
Valid values: path to a write-enabled log file
Default value: not set
