| Core functionality | Core features supported by all ICA clients are: 1280x1024 resolution 24-bit color depth Memory and persistent (disk) cache TCP/HTTP server browsing Disconnect/ reconnect support Encryption up to 128 bits International keyboard support |
| Seamless windows | A published application appears as if it is running locally on the client's desktop. |
| Text Entry Prediction | SpeedScreen feature that provides the user with instant feedback to text entry regardless of whether the data transmission from the server is complete. |
| Panning | A client window can be set larger than the actual client desktop size . Panning allows the user to scroll the desktop view around to see different portions at one time. |
| Scaling | A larger client session can be shrunk to display within a smaller client device desktop size. |
| Browser Acceleration | SpeedScreen feature that enhances processing of graphics in a web browser (Internet Explorer 5.5 or later) or email (Outlook or Outlook Express). |
| Multimedia Acceleration | SpeedScreen audio and video acceleration. Multimedia files are sent compressed to the client, and client-side resources decompress and play the content. This feature requires Enterprise or Advanced Editions of Presentation Server. |
| Image Acceleration | SpeedScreen feature. Images are compressed before sending them to the client. |
| Flash Acceleration | SpeedScreen feature. Macromedia Flash animation is rendered in a low-quality mode and sent to the client. This feature requires Enterprise or Advanced Editions of Presentation Server. |
| Dynamic Session Resizing | A desktop session can be dynamically resized by the user on the fly. |
| Client Device Mapping | This feature allows access to the local client device from within the MetaFrame session. The supported devices include drives , printers, COM ports, audio (client to server and server to client), and the Clipboard. |
| Auto Client Reconnect | If a client is disconnected due to a network or device failure, the client automatically attempts to reconnect to the server. |
| Roaming User Reconnect | If a user moves from one device to another, the user's session (active or disconnected) is automatically transferred from one location to the other when the user logs on. |
| Auto Client Update | This feature automatically updates the client based on settings in the Client Update Database. |
| Extended Parameter Passing | This feature allows the association of a local file type with a published application. It requires configuration on both the client and server to function properly. This feature provides functionality equivalent to client/server content redirection, a feature available only with PN Agent. |
| Content Publishing | This feature supports accessing content besides applications. Published content can include any type of file including documents, web links, or media files. |
| Content Redirection (Client to Server) | This feature enables integrated support only through PN Agent and requires Enterprise or Advanced Edition of Presentation Server. It allows local file associations to open applications published in the farm. |
| Content Redirection (Server to Client) | Server-based file associations can open applications that run locally on the client device. For example, a web link could be opened using a local Internet Explorer instead of the browser on the server. |
| Auto Printer Detection | This feature automatically detects and maps client printers in the MetaFrame session. |
| Universal Printer Driver | This feature substitutes a Citrix universal printer driver for the native driver associated with a client printer. |
| Session Reliability | A feature that shields users from connection interruptions by setting the cursor to an hourglass and displaying an image of the user's session while it automatically attempts to re-establish a connection with the server. |
| SmartCard support | This feature allows authentication using a SmartCard and PIN. |
| NDS support | This feature allows authentication using Novell Directory Services. |
| SSL/TLS | This feature provides Presentation Server connectivity through the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) security protocols. |
| SOCKS 4/5 proxy support | This feature provides client connectivity through a SOCKS version 4 or 5 proxy server. |
| Auto Proxy Discovery | The ICA client attempts to retrieve the proxy settings from the default web browser for the device. If the default browser is IE and is configured to automatically detect settings, the Win32 client ignores these settings and attempts a direct connection. |
| Secure Proxy | This feature supports connectivity through a Secure Proxy server. A secure proxy server uses SSL tunneling. |
| NTLM Proxy Authentication | When a proxy server supports NTLMv2 authentication, a Win32 client can provide the necessary credentials. Otherwise, only basic proxy authentication is supported. |
| Pass-through Authentication | This feature supports the use of local user credentials to automatically authenticate and access resources on the server. |
| Time Zone Support | The local time zone of the client device can be detected and used to display the appropriate local time for the user on the server. |
| Enhanced Unicode Keyboard Support | Enhanced keyboard support allows for input of text using alternate methods such as handwritten text entry or Microsoft Input Method Editors (IMEs), which allow input of foreign language characters such as Japanese characters on a standard keyboard. |
| Multiple Server Farm Support | The Web Interface and Program Neighborhood Agent support simultaneous access to applications within different server farms. |
| End-user Change Password | User password change support is provided from within the Web Interface. |
