1.3 Optional Packages 7

1.3.6 Source

Conﬁguration File: N/A

Documentation: N/A

Description: The source package (secureweb-source) contains the

Apache source code for your secure web server. You need to install

source if you plan on including an extra module that needs the

source code in order to compile. See section 2.5 on page 34 for more

information about including modules using Apache’s DSO support.

Unless you plan on compiling and loading a module which will re-

quire the source code, you do not need to install this package. Most

modules will notneed the source code inorder to compile. If you do

install thispackage, however, you will also needto installthe devel

package.

1.3.7 Squid

Conﬁguration File: /etc/squid.conf

Documentation: /usr/doc/squid-1.1.22/

Description: Squid is a proxy caching server for web clients which sup-

ports HTTP, FTP and gopher data objects. Squid keeps meta data,

popular objects, andDomain Name Server (DNS) lookups cached in

RAM (oron disk if youdon’t have the memoryto spare). Squid sup-

ports non-blocking DNS lookups and implements negative caching

of failed requests.

Using Squid, you can set web browsers to use your web server as a

proxy server. Obviously, this is only useful if you have more than

one person using it or you repeatedly visit the same web pages.

Squid will cache requests so that if you access a site more than once,

the subsequent retrievals will be much faster. The second and sub-

sequent retrievals will be retrieved from the proxy server’s memory

instead of from the actual website.

When you install the squid package, you can choose whether to

install the memory caching version (if you have memory to spare)
