Functional Features

Application Security

Capable to carry out two-way in-depth test for HTTP / HTTPS data streams, with full analysis capabilities for HTTP / HTTPS protocol;

Able to effectively defense malicious tampering to websites, including SQL injection, cross-site scripting, information leakage, directory traversal vulnerability, cookie counterfeiting, command lines injection, remote file inclusion, version detection for operating system and application server;

Checking on details of the HTTP protocol, including HTTP protocol version, method and URL parameters;

Able to prevent application DDOS attacks and slow DDOS attacks against Web server, supporting anti-brute attack;

Providing server information camouflage / filter to avoid exposure of sensitive information or error messages.

Application Acceleration

Supporting caching of RAM-based HTTP objects, which significantly enhance the access speed for users and reduce the pressure of application server.

Supporting HTTP traffic compression with a compression ratio of up to 80%, reducing bandwidth consumption and shortening the download time for end-users with a slow / low bandwidth;

Supporting URL hashing algorithm specially set for the cache server, improving URL hit rate of cache server effectively;

Supporting SSL offload, reducing load of the server, thereby improving the performance and reducing the server resource consumption of each user.

High Availability of Application

Seven-Layer load balance

Supporting smooth joining and exit of the application servers, without affecting existing business applications;

Supporting customized the policy on flow distribution, rewriting the request or any part of the response;

Supporting URL redirection, HTTP request filtering, user-defined HTTP error pages;

Supporting load balancing algorithms such as polling, weighted polling, minimum connections, weighted minimum connections, hash and shortest response time;

Supporting session persistence based on source IP / Cookies, so that requests of specific client can be always assigned to the same server for processing;

Supporting maximum connection limit and concurrent connection limit to avoid server overload;

Supporting smooth joining and exit of the server, which makes maintenance and management more convenient;

Supporting self-signed data certificates and third-party CA certificates.

Four-Layer load balance

Widely applicable to a variety of TCP-based applications;

Supporting polling, weighted polling, minimum connections, weighted minimum connections, source address hash and other load balancing algorithm;

Supporting the session persistence policy based on source address;

Assigning specific routing mode and triangular transfer mode to each virtual site.

Server Health Check

Equipped with ample service health check mechanism, providing user-defined script check according to clients' applications, able to carry out in-depth service health check, and ensuring that data traffic will automatically bypass the failed server or unavailable server;

Embedded health check algorithms for TCP, HTTP and other protocols;

Supporting user-defined health check for scripts, applicable to all applications based on TCP or UDP.

Management & Report

Providing secure browser-based access and SSH remote network management, in order to configure and monitor devices; supporting Syslog log management and providing an interface for third-party management;

Users are separated from roles, achieving the fine grit account management and providing complete system audit logs;

Supporting dual active to avoid single point failure;

Supporting mail-based alarm during failure of server and application system to accomplish immediate maintenance of normal operation;

Providing web traffic record, number of visits, number of concurrent connections and other data; noting administrators of server load directly. With server stability reports, administrators could view the status of each node server (normal, busy or failure) and make adjustment in time.
