HOR-433 "(WSSO Plugin) Cuando se ingresa al proceso, se..." SOLVED

Issue:
    (WSSO Plugin) Cuando se ingresa al proceso, se puede verificar que no se puede recuperar la data del mismo
Cause:
    Se esta usando el mismo VirtualHost para clientes WEB y REST
Solution:
    Se realizo la implementacion de la nueva directiva "server_hostname_requests_frontend" del "env.ini"; esto para
    el caso en que se requiera del "feature SSO", tomar nota de lo siguiente:
        - Habilitar el modulo "mod_headers" de apache (httpd.conf)
        - Tener configurado un VirtualHost normal para ProcessMaker (pmos.conf)
        - Para el "feature SSO" se debera crear un 2do VirtualHost con toda la configuracion necesaria para
          el mismo (pmos.conf), por lo que todos los usuarios que requieran este feature, deberan usar este para
          acceder por browser
        - Crear un 3er VirtualHost para las solicitudes del front-end (DESIGNER), en donde se agregara lo
          siguiente (pmos.conf):
              <IfModule mod_headers.c>
                  Header set Access-Control-Allow-Origin  "*"
                  Header set Access-Control-Allow-Headers "Content-Type,Depth,User-Agent,X-File-Size,X-Requested-With,If-Modified-Since,X-File-Name,Cache-Control,Authorization"
                  Header set Access-Control-Allow-Methods "OPTIONS,GET,POST,PUT,DELETE"
              </IfModule>
          De tal forma que quedara asi:
              <IfModule mod_headers.c>
                  Header set Access-Control-Allow-Origin  "*"
                  Header set Access-Control-Allow-Headers "Content-Type,Depth,User-Agent,X-File-Size,X-Requested-With,If-Modified-Since,X-File-Name,Cache-Control,Authorization"
                  Header set Access-Control-Allow-Methods "OPTIONS,GET,POST,PUT,DELETE"
              </IfModule>
              <IfModule mod_rewrite.c>
                  RewriteEngine On
                  RewriteCond %{REQUEST_FILENAME} !-f
                  RewriteRule ^.*/(.*)$ app.php [QSA,L,NC]
              </IfModule>
        - Agregar lo siguiente al archivo "/path/to/processmaker/shared/sites/your-workspace/env.ini"
              server_hostname_requests_frontend = "{your_server_hostname_requests_frontend}"
          Donde:
              - your_server_hostname_requests_frontend, es el nombre del servidor configurado para el
                front-end (3er VirtualHost), ejemplo:
                    server_hostname_requests_frontend = "192.168.40.72:3017"
        - Tambien se puede hacer la configuracion en el archivo "/path/to/processmaker/workflow/engine/config/env.ini",
          considerar que esto afectara a todos lo workspaces creados
Note:
    Todo el desarrollo se lo hizo en un server Windows-Server-2012-R2 con Apache-2.4
