• Apache 1.3.X or higher or Microsoft IIS 5.0 or higher.
• MySQL 4.1.11 or higher, or Oracle 10g or Microsoft SQL Server 2000 or higher.

	All commercial versions of our products are supplied in full source code.

* All software packages required by Bitrix Site Manager are available on the vendor web sites for free (except commercial version of Oracle and MSSQL) and are also included in the Bitrix Environment package.

Recommended Software Requirements

• PHP 5.0.0 and higher. We recommend using the latest stable release of PHP.
  The following PHP extensions are required:
  
  • GD – image handling library;
  • PHP XML – used by the update system;
  • FreeType – required for CAPTCHA;
  • Regular Expressions support;
  • Zlib compression – required to decrease the amount of transferred data;
  
  
• PHP enabled web server:
  • Apache (recommended) 1.3.X and higher. The system also runs successfully on Apache 2.X;
  • MS IIS 5.0 or 6.0. PHP should be installed as ISAPI.
  
  
• Database server support. One of the following database engines can be used on your site:
  • MySQL version 4.1.11 and higher is recommended. To work with MySQL properly, the system requires the MySQL support for PHP to be installed;
  • Oracle 10g can be used. To fully support Oracle, the php_oci8.dll extension of PHP should be installed;
  • MSSQL 2000 and higher can also be used. ODBS support should be provided to be able to install this database.
• Zend Optimizer 3.0 or higher. Note that Zend Optimizer is needed only for installing the trial version of Bitrix Intranet Portal. The commercial version of Bitrix Intranet Portal is supplied with the full source code and there is no need to have Zend Optimizer installed.

Memory limit

Please note! One of the critical PHP parameters that Bitrix Intranet Portal requires for proper functioning is memory_limit = 32M. This is the minimum amount of PHP memory required by the system core.
This parameter can be changed:

• by editing the file php.ini directly;
• from within a script by calling ini_set("memory_limit", "64M");
  This call is added to /bitrix/php_interface/dbconn.php at the installation time using the user-supplied value;
• in the file .htaccess using the directive: php_value memory_limit 64M.

Web Browser Support

All the site management tasks can be performed through the web-interface of any Internet browser (except when working with the HTML editor component, which requires Internet Explorer 7.0 and higher or Mozilla Firefox 1.5 or higher). Bitrix Intranet Portal supports the following standards:

• HTML/XHTML – the system places no restrictions on templates developed with HTML/XHTML;
• JavaScript – the system unconditionally supports the use of JavaScript in the site templates, menus and pages;
• AJAX – this technology is widely used in the Control Panel to speed up the system response and decrease server-to-client data traffic. The system places no restrictions on using AJAX in the public section;
• CSS can be used in the in site template design, public components, etc. The Control Panel features the use of visual themes: users can create their own visual themes through customized cascading styles.
• Flash technology support is limited. You can use it as a part of the site template design, as advertising banners, or as user input controls deliberately designed to interact with the system.
• RSS (versions 0.92 or 2.0) is used to exchange information between the Information Blocks and Blogs modules.
• CSV standard is used to exchange information between the Information Blocks module and other systems.
