EWF Deployment

##Apache on Windows ###Apache Install

• Check the correct version (Win 32 or Win64)
• Apache Version:  Apache 2.4.4
• Windows: http://www.apachelounge.com/download/

###Deploying EWF CGI

####CGI overview

A new process is started for each HTTP request. So if there are N request to the same CGI program, the code of the CGI program is loaded into memory N times. When a CGI program finished handling a request,  the program terminates

1. Build EWF application.

   ec ­config app.ecf ­target app_cgi ­finalize ­c_compile ­project_path .
   Note: change app.ecf and target app_cgi  based on your own configuration.
   

2. Copy the generated exe file and the www content.

   Copy the app.exe and the folder www into a folder served by apache2, for example under
   <APACHE_PATH>/htdocs
   <APACHE_PATH> = path to your apache installation
   Edit httpd.conf under c:/<APACHE_PATH>/conf
   DocumentRoot "c:/<APACHE_PATH>/htdocs"
   <Directory "c:/<APACHE_PATH>/htdocs">
   AllowOverride All --
   Require all granted -- this is required in Apache 2.4.4
   </Directory>
   

3. Check that you have the following modules enabled.

   LoadModule cgi_module modules/mod_cgi.so
   LoadModule rewrite_module modules/mod_rewrite.so
   

Tip: To check the syntax of your httpd.conf file. From command line run the following.

```
$>httpd - t
```

####.htaccess CGI http://perishablepress.com/stupid­htaccess­trics/

    Options +ExecCGI +Includes +FollowSymLinks ­Indexes
    AddHandler cgi­script exe
    <IfModule mod_rewrite.c>
       RewriteEngine on
       RewriteRule ^$ $service [L]
       RewriteCond %{REQUEST_FILENAME} !­f
       RewriteCond %{REQUEST_FILENAME} !­d
       RewriteCond %{REQUEST_URI} !$service
       RewriteRule ^(.*)$ $service/$1
       RewriteRule .* ­ [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
    </IfModule

Replace $service with the name of your executable service, for example app_service.exe

##Deploying EWF FCGI

• To deploy FCGI you will need to download the mod_fcgi module.
• You can get it from here http://www.apachelounge.com/download/

###FCGI overview

FastCGI allows a single, long­running process to handle more than one user request while keeping close to the CGI programming model, retaining the simplicity while eliminating the overhead of creating a new process for each request. Unlike converting an application to a web server plug­in, FastCGI applications remain independent of the web server.

1. Build EWF application

   ec ­config app.ecf ­target app_fcgi ­finalize ­c_compile ­project_path .
   Note: change app.ecf and target app_fcgi  based on your own configuration.
   

2. Copy the generated exe file and the www content

   Copy the app.exe and the folder "www"  into a folder served by apache2, for example under
   <APACHE_PATH>/htdocs.
   <APACHE_PATH> = path to your apache installation
   Edit httpd.conf under c:/<APACHE_PATH>/conf
   
   DocumentRoot "c:/<APACHE_PATH>/htdocs"
   <Directory "c:/<APACHE_PATH>/htdocs">
      AllowOverride All --
      Require all granted -- this is required in Apache 2.4.4
   </Directory>
   

Check that you have the following modules enabled.

```
LoadModule rewrite_module modules/mod_rewrite.so
LoadModule fcgid_module modules/mod_fcgid.so
```

By default Apache does not comes with fcgid module, so you will need to download it, and put the module under Apache2/modules

####.htaccess FCGI http://perishablepress.com/stupid­htaccess­tricks/

    Options +ExecCGI +Includes +FollowSymLinks ­Indexes
    <IfModule mod_fcgid.c>
      AddHandler fcgid­script .ews
      FcgidWrapper $FULL_PATH/$service .ews
    </IfModule>
    <IfModule mod_rewrite.c>
       RewriteEngine on
       RewriteBase /
       RewriteRule ^$ service.ews [L]
       RewriteCond %{REQUEST_FILENAME} !­f
       RewriteCond %{REQUEST_FILENAME} !­d
       RewriteCond %{REQUEST_URI} !=/favicon.ico
       RewriteCond %{REQUEST_URI} !service.ews
       RewriteRule ^(.*)$ service.ews/$1  RewriteRule .* ­ [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
    </IfModule>

Replace $service with the name of your executable $service, for example app_service.exe You will need to create an service.ews file, this file will be located at the same place where you copy your app service executable.
