Glossary of Internet Terms and Phrases
- A cache (pronounced CASH) is a place to store something temporarily. The
files you automatically request by looking at a
Web page are stored on your hard disk in a cache subdirectory under the
directory for your
browser (for example, Internet Explorer). When you return to a page
you've recently looked at, the browser can get it from the cache rather than
server, saving you time and the network the burden of some additional
traffic. You can usually vary the size of your cache, depending on your

- An entity (typically a company) that issues
digital certificates to other entities (organizations or individuals) to
allow them to prove their identity to others. A Certificate Authority might
be an external company such as VeriSign that offers digital certificate
services or they might be an internal organization such as a corporate MIS
department. The Certificate Authority's chief function is to verify the
identity of entities and issue digital certificates attesting to that

- A computer system or process that requests a service of another computer
system or process (a "server")
using some kind of
protocol and accepts the server's responses. A client is part of a
client-server software architecture.
For example, a workstation requesting the contents of a file from a file
server is a client of the file server.
- An application development tool from Macromedia for writing
Web pages that interact with
databases. Instead of writing tedious
Perl scripts, operations are coded in the ColdFusion Markup Language (CFML)
HTML-like tags embedded in the Web pages. The ColdFusion engine, which
interfaces with a Windows-based Web server, interprets the codes, accesses
the database and delivers the results as HTML pages for the Web
browser. ColdFusion was originally developed by Allaire Corporation,
Cambridge, MA, which merged with Macromedia in 2001.

Common Gateway Interface (CGI)
- A standard for running external programs from a
World Wide Web
HTTP server. CGI specifies how to pass arguments to the executing
program as part of the HTTP request. It also defines a set of environment
variables. Commonly, the program will generate some
HTML which will be passed back to the
browser but it can also request
CGI allows the returned HTML (or other document type) to depend in any
arbitrary way on the request. The CGI program can, for example, access
information in a
database and format the results as HTML. A CGI program can be any
program which can accept
command line arguments.
Perl is a common choice for writing CGI scripts. Some HTTP servers
require CGI programs to reside in a special directory, often "/cgi-bin" but
better servers provide ways to distinguish CGI programs so they can be kept
in the same directories as the HTML files to which they are related.
server receives a CGI execution request it creates a new process to run
the external program. If the process fails to terminate for some reason, or
if requests are received faster than the server can respond to them, the
server may become swamped with processes.
In order to improve performance, Netscape devised NSAPI and Microsoft
developed the ISAPI standard which allow CGI-like tasks to run as part of
the main server process, thus avoiding the overhead of creating a new
process to handle each CGI invocation.
