WebServer
The iTP Secure WebServer provides a full range of services for running an online

The iTP Secure WebServer’s key features are as follows:
•
High performance
The iTP Secure WebServer’s high-performance, multithreaded architecture
provides low-latency response to multiple clients simultaneously. Persistent
connections can provide significant performance gains in comparison with a
separate connection for each request.
•
Caching at several levels
To improve performance, the iTP Secure WebServer caches files it accesses. Disk
file access is one of the most common and expensive operations in a web server.
Therefore keeping these files in memory will save a lot of CPU utilization, and
improve overall performance. In addition to file opens, already cached, the file
information as well as the actual file content can also be cached.
•
Encryption and authentication flexibility
The iTP Secure WebServer supports the use of the HTTP, SSL, PCT, and
hardware-based cryptography provided by WebSafe2 units. Secure HTTP supports
the simultaneous use of both the SSL and HTTP protocols. These options give you
maximum flexibility in protecting the privacy and integrity of your server’s
interactions with clients. The iTP Secure WebServer implements both encryption
and digital signatures.
•
Flexible access control
You can control access to the iTP Secure WebServer on the basis of such factors
as host name, time of day, user name, browser type and version, and
authentication method.
