How to Become a Mirror of the Apache Web Site

Requirements

It is easy to become a mirror. There are only a couple of requirements:

You must carry the complete site.
You must do an update-check at least twice a week.
You must subscribe to the mailing list for mirror maintainers.

More requirements may be placed at some point in the future, but for now that's all there is. There are a couple things which are highly recommended:

Run your mirroring software between midnight and 4am Pacific Standard Time (8am-noon GMT) when traffic to www.apache.org is at its lowest.
Consider setting up both a web site and FTP site, at least for the /dist directory.

Strategy

There are a couple different ways to mirror a remote web site:

Use the proxy module in Apache to "pass-through" requests to the central Apache web site. Set up the following in the configuration for your mirror:
```
ProxyPass / http://www.apache.org/
CacheDefaultExpire 24
```
Every request which then comes into this server will be passed along to www.apache.org, unless the object is already in your local cache and is less than 24 hours old.
Use the FTP-based "mirror.pl" package, available at ftp://src.doc.ic.ac.uk/computing/archiving/mirror, as well as at ftp://ftp.debian.org/debian/stable/source/net/. If you use this, point the package at ftp://ftp.apache.org/apache/. There is also "Wget", a package available from most GNU mirrors.

We do not recommend the use of Web spiders, or HTTP equivalents to the "mirror.pl" package, as every object needs to get a HEAD request every time it is checked, which is a very inefficient mechanism for seeing what's been updated on an entire site.

There are some other requirements for serving files obtained via FTP:

Make sure your mirror.pl script has "mode_copy=true" to ensure permissions preservation.
Set the configuration DocumentIndex index.html index.cgi, or DocumentIndex index if Options MultiViews is set.
Please enable server-side includes, i.e. Options Includes or Options IncludesNoExec.

Inform us!

Once the site is set up, send mail to apache@apache.org to let us know it's been set up, and we'll add it to the list of mirrors.

The mailing list for mirror maintainers can be joined by sending mail to "majordomo@apache.org" with the words "subscribe mirrors" in the body of the message.

Good luck!
