Mirroring Software
A mirror of a site is a partial or full copy of the pages of that
site. There are many reasons for having a mirror:
- to distribute the load on your server
- to reduce the access time for your users by putting a
copy close to their geographical location
- to provide a backup of your information
- to separate your development area from your "live" pages
For larger sites, such as The WDVL,
it is necessary to have software to help manage this. There are
a number of software packages available for the various server
platforms to help you perform this function.
Currently, we use a combination of Perl scripts and Unix commands to
maintain our
mirror site.
Our pages are actually generated by a pre-processor,
ht.
As this script is run on our main site,
the date and file name, including the
directory path, are written to a list of updated files. When
we are ready to update the mirror, the list of files is analyzed
and a tar file of the modified files generated, along with a Unix
shell script to call the pre-processor on the mirror.
This method is more
person intensive than the software packages, but it enables us to
customize each site and we like it.
