Using Environmental Variables With WebPB Introduction Environmental variables provide information about the client and web server environments. Different variables are defined for different functionality. The get method appends the URL with the arguments and values sent to the web server from the brower. The post method uses standard input to pass the data to the web server. Since it sends the data in a separate stream, there is no variable limitation.
Conclusion Review the web server documentation.
Web servers are configured differently. They may use different environmental variables and pass data thru standard input differently.
