virtual path/mkscgi.exe/virtual path/file
mkscgi provides a facility for running KornShell scripts on HTTP servers through the Common Gateway Interface (CGI). mkscgi also executes any binary and script when they have a registry association.
mkscgi parses content returned from an HTML form, and converts each field into a WWW_ environment variable. It then executes the binary associated with the script specified in extended path information of the HTML form statement. For example, for the form statement
<form method="POST" action="/cgi-bin/mkscgi.exe/cgi-bin/mkscalc.ksh">
mkscgi reads the content returned from the browser, parses each field into a WWW_ environment variable, then passes those environment variables through to the script. Additionally, all system environment variables are expanded and passed to the script.
In the above example, the directory name (cgi-bin) following mkscgi.exe is a virtual path defined by the server administrator. The server expands the virtual path into the environment variable PATH_TRANSLATED.
Use registry to make the registry association for a custom script extension and binary:
registry -s -k 'HKEY_CLASSES_ROOT\.ext' -n '' -v 'string_value' registry -s -k 'HKEY_CLASSES_ROOT\string_value\Shell\Open\Command' -n '' -v 'custom.exe %1'
For scripts with extensions .ksh and .sh, the shell specified in the SHELL environment variable is executed directly and not looked up in the registry.
mkscgi is not a command line utility. mkscgi uses system variables which are defined by HTTP servers and must therefore be launched by an HTTP server.
Several example HTML and script files are included with PTC MKS Toolkit. If they were not installed during setup and are not located in $ROOTDIR/mksnt/www, then run PTC MKS Toolkit setup.exe. At the Setup Type window choose Custom to install the Internet Server Support files.
Basic installation of the example scripts assumes that your HTTP server is configured to have a dedicated CGI directory and that PTC MKS Toolkit is installed.
No changes or additions are required to browser mime types or to the registry. First put the files into the right directories and then write your own .htm and .ksh scripts.
- Place mkscgi.exe and the example .ksh files into the dedicated cgi-bin scripts directory.
- Copy the .htm files and any files to download into the document root directory. Back up your default index.html or home.htm. Copy mksdemo.htm to index.html or home.htm.
- mksvalid.pl and mksdnld.ksh must be configured with the server name and the name of the file to be download.
- Use your browser to link to the server.
Browser form content is parsed by mkscgi and placed into the environment. Each form field name is prefixed with WWW_. If a field name begins with an underbar, one underbar is removed. Dots in a field name are converted to underbars.
User defined in .html file. Must be defined as POST or GET.
Contains form content if REQUEST_METHOD is GET. If REQUEST_METHOD is POST it can contain the URL-embedded constant information. mkscgi does not process this embedded information.
Set by your web server.
Full path name of the specified script. The form statement extra path information contains a virtual path which is expanded by the server.
Full path name of sh.exe.
Full path name of MKS Toolkit's root directory.
Possible exit status values are:
Failure due to any of the following:
- — environment variable [variable] normally set by HTTP server not correctly set
- — form method must be POST or GET
- — your browser didn't send any content
- — could not allocate memory
- — cannot determine script to run because PATH_TRANSLATED is not set
- — failed to run shell
- — insufficient memory
- — error finding script extension in registry
- — error reading script extension value from registry
- — error finding binary association in registry
- — error reading binary association from registry
- — form data is corrupt
- — invalid escape sequence in value
- — unable to read system environment variables from registry
- — error expanding registry system environment variables
- — system environment variable too long
mkscgi attempts to send any error messages back to the client browser.
