-<VirtualHost *:80>
-	ServerName sdciblage.sd.dev
-	AddDefaultCharset utf-8
-	DirectoryIndex index.php
-	SetEnv APPLICATION_ENV "development"	
-	DocumentRoot "WORKSPACE/sdciblage/public"
-	<Directory "WORKSPACE/sdciblage/public/">
-		AllowOverride none
-		Order allow,deny
-		Allow from all  
-		<IfModule mod_rewrite.c>
-            RewriteEngine On
-            RewriteCond %{REQUEST_URI} ^/favicon.ico$ [OR]
-            RewriteCond %{REQUEST_FILENAME} -s [OR]

-	LogLevel notice
-	ErrorLog "logs/sdciblage-error.log"
-	CustomLog "logs/sdciblage-access.log" common
-</VirtualHost>
+    session.gc_maxlifetime = 86400
+    session.cookie_lifetime = 86400
