public class FastCGIProxyServlet
extends AsyncProxyServlet.Transparent

Specific implementation of AsyncProxyServlet.Transparent for FastCGI.

This servlet accepts an HTTP request and transforms it into a FastCGI request that is sent to the FastCGI server specified in the proxyTo init-param.

This servlet accepts these additional init-params:

• scriptRoot, mandatory, that must be set to the directory where the application that must be served via FastCGI is installed and corresponds to the FastCGI DOCUMENT_ROOT parameter
• scriptPattern, optional, defaults to (.+?\.php), that specifies a regular expression with at least 1 and at most 2 groups that specify respectively:
  • the FastCGI SCRIPT_NAME parameter
  • the FastCGI PATH_INFO parameter
• fastCGI.HTTPS, optional, defaults to false, that specifies whether to force the FastCGI HTTPS parameter to the value on
• fastCGI.envNames, optional, a comma separated list of environment variable names read via System.getenv(String) that are forwarded as FastCGI parameters.
