PLBWEB_REST_USE_FCGI Keyword

10.2

     PLBWEB_REST_USE_FCGI<nn>={parameter}

This keyword controls the REST task interface used by the PWS server.

This keyword is optional and is placed in the [Environment] section of the PWS configuration INI file.

Where:

nn

The 'nn' that is appended to the PWS keyword name can be a string value from '01' to '99'.

parameter

The parameter can be specified as 'ON', or 'OFF'.

Note:

1.   When this keyword is set to OFF, the PL/B REST service uses the CGI interface.  This is the default behavior if this keyword is not used.

2.   The CGI interface creates a new process for each request.

3.   When this keyword is set to ON, the PL/B REST service uses the FastCGI interface.

4.   The FastCGI uses persistent processes to handle a series of requests.

5.   Each REST FastCGI process is started when the PWS starts.

6.   If a FastCGI process fails, it is locked out. This reduces the PLBWEB_REST_MAX_COUNT by one. Optionally, an error is logged and an email message is sent when the administrative email services are enabled.

Example:

PLBWEB_REST_USE_FCGI=ON
