Why wait for web pages to be delivered from thousands of miles away when you could have them delivered from your own LAN? Web caching improves browsing speed for LANs of all sizes. We invite you to try Vicomsoft's SoftRouter and see for yourself.

	Server-Based Web Caching – Faster web browsing for LAN-based users. With Efficient use of Internet bandwidth
	Transparent connection to the WebCache – No setup required for LAN client browsers
	Local and Remote Administration of WebCache – Administrator can administer the WebCache both from the server computer and optionally remotely using a browser
	Grant Administrator Privileges on server by server basis – Control users access to features
	Concurrent Caching and Delivery – Faster content delivery to LAN browsers

Benefits:
Faster web browsing for LAN-based users
Efficient use of Internet bandwidth

Description:
Normally, every time the same web page is requested by more than one user on the LAN, all the content must be delivered once again across the Internet with each user experiencing the often frustrating 'Internet delays'. The Vicomsoft WebCache module saves recently viewed pages on your LAN and then sends these pages when a request is made which dramatically reduces the time taken to redisplay the same page.

Detail:
Web content is delivered from remote web servers to users' browsers across the Internet. The faster this happens, the better for the user. However, between the remote web server and a user's browser the content may travel over many networks of varying size and complexity. For each element (text, graphic, video, sound) on a web page the browser must transmit a request and the server must deliver the content. Any delay in either the transmission of the request or the delivery of the content will increase the amount of time the user must wait. The total time required to display a full web page will depend on a number of factors which, for the sake of discussion we refer to as 'Internet Delays' and which include:

• the speed with which the remote server delivers web content
• the number of concurrent requests the remote server is responding to
• the way the remote site allocates bandwidth to serve requests
• available bandwidth from the remote site to the Internet backbone
• congestion on the Internet backbone
• available bandwidth and congestion between the ISP and the Internet backbone
• available bandwidth between the user's LAN and its ISP

Each time a web page is requested by another user on the LAN the content must be delivered once again incurring delays due to any or all of the above factors.

The Vicomsoft WebCache Module reduces Internet Delays by storing copies of the web content on the user's LAN. The WebCache dramatically improves web browsing response times through rapid delivery of frequently accessed web content from a high performance caching server. Delivery of content from the cache can be as much as five to ten times faster than from the Internet over a T1 connection, and over one hundred times faster than with a 56Kbps modem. Using the new WebCache frees bandwidth for the delivery of fresh content as well, significantly improving response time and efficiency for networks of all sizes.

Benefit:
No setup required for LAN client browsers

Description:
Traditionally, caching servers were combined with proxy servers and required manual configuration of client applications such as web browsers. Vicomsoft Internet connectivity server products are the first to combine the best features of NAT routing (which does not require LAN-client setup) with a web caching server using unique 'transparent connectivity' technology. Now, for the first time, users can benefit from caching while network administrators do not have to reconfigure each client browser. The setup experience is further enhanced when TCP/IP on each LAN client is configured to use the DHCP Server integrated in the Vicomsoft routers. This combination of features and technologies provide true 'plug-and-play' installation and use.

Benefit:
Administrator can administer the WebCache both from the server computer and optionally remotely using a browser.

Description:
The Vicomsoft WebCache module has both local and remote administration capabilities. For local administration it incorporates a built-in easy-to-use administrator's interface accessed on the server computer where it is installed. The administrator can optionally enable the remote administration facility which allows administration to be done using a web browser.

Benefit:
Allow users to administer individual servers related to their job function.

Description:
The Vicomsoft WebCache now allows the administrator to grant sub-administrator access privileges. These can be granted selectively for the WebHeader Server, the Web Caching Server, the Off-line CacheLibrary, and the Local TCP Server Locator. Now you can grant access to administrative functions for one server whilst retaining control of the others.

Benefit:
Faster content delivery to LAN browsers

Description:
The Vicomsoft WebCache module incorporates innovative design that provides concurrent delivery and caching of incoming data as well as concurrent delivery to multiple LAN clients. This exclusive multistreaming technology assures faster delivery of both cached and fresh content compared with traditional proxy servers which sequentially cache content before delivering to clients thereby introducing noticeable delays. Vicomsoft technology ensures that fresh content is delivered with no additional delays while at the same time providing the benefits of caching.
