Japt-Proxy is a JAVA(TM) based Caching Proxy for Debian's APT-System. Japt-Proxy is lightning fast and very reliable. Japt-Proxy is usually used in environments where several Debian systems have to be kept up-to-date without downloading the same files over and over again from the debian mirrors. Mostly these environments are data centers, Linux-powered companies, schools, public authorities and so on.
Often Japt-Proxy is used because of small sized internet connections but it is also useful to install complete debian systems over the net (read: over the proxy). Even with high volume internet connections Japt-Proxy can dramatically reduce the time to install or update Debian on many machines.
I know there are people out there thinking "Hey? Why Java?". There are a bunch of reasons why people asking those questions. I have a simple answer to all those questions. The answer is, that Java enabled me to easily develop the fastest and most reliable APT-Proxy. Java and the Apache Software Foundation provides such good libraries for this job, that it wasn't very hard to bring up this tool.
If you don't trust, test it - the installation takes less than five minutes!
No, it doesn't. Japt-Proxy knows the characteristics of a Debian archive and their files. It knows, for example, that .deb files won't change, because newer files would have a new name (the version is always part of the filename), hence it won't recheck if there is a newer version of this specific file.
Furthermore you can configure the Japt-Proxy to delete old versions of a package in its cache directory - a general proxy cache would simple delete files that haven't been requested for some time.
So, a general caching proxy like Squid is a perfect tool for caching "normal" internet traffic. If you need a proxy for faster APT access - Japt-Proxy is the right tool for you.
