Gnutella Web Caching System
The Gnutella Web Caching System, or GWebCache, is a simple but powerful web-based distributed host caching system designed to support the Gnutella network. It was developed with Gnucleus, and since it is a simple, open system, we invite anyone to use it.
March 2008 - Long Time No See
After this much time I'm happy to see that there are still GWebCaches kicking around! As those of you who were involved with GWebCache at the time certainly figured out, after the whole clients-destroying-GWebCache-servers thing I pretty much stopped working on the project. Because, happily, others seem to have picked up on the development, this website should no longer be considered the central GWebCache page, it is here for historical purposes only. Since I don't intend to maintain this website, it's up to you to find the other GWebCache pages out there (see the links above for some pointers though).
So what happened back then? GWebCache is a script that invites requests from file-sharing clients. These clients are installed on tens of thousands - if not hundreds of thousands or even millions - of computers. If these clients had a bug that caused them to send too many requests, the effect is a massive distributed attack on GWebCache servers. This is exactly what happened: at least one client was badly programmed and the company and developers were completely unresponsive, creating a very bad situation for GWebCache users: The client sent a massive number of requests to GWebCaches, people's web servers got taken down, either by their administrators or simply by the massive number of requests that overloaded them, they were charged for the bandwidth consumed, and so on.
Since I spent around a year fighting the massive number of requests on my own web server that simply would not stop, I also stopped working on the project. While that is unfortunate and I don't like abandoning projects, I didn't feel like I could continue at the time; in the meantime I moved on to many other projects. I am happy to see that GWebCache has survived and lives on!

6.10.2003 - GWebCache 2 Released (updated March 2008)
I am releasing the GWebCache "version 2" script and the new specifications. Both seem stable, but need to be implemented in clients and tested. Hopefully someone (you?) will have the time to do so!
You can download GWebCache 2 (Perl) here. Please note the following important points:
Many people have been asking on how to report their new GWebCache to the world. One way to do it is the following:
Also, many people have been asking on how to remove their GWebCache and stop the requests, the sad answer is: unless the clients that are abusing your cache don't stop (which they haven't, for more than half a year now), you can't. At least not without taking down your website, which is why I say above to host the GWC on a dedicated subdomain!
Also, the official GWebCache site is now located here on gnucleus.com (http://www.gnucleus.com/gwebcache/) - update your links! (gnucleus.net seems to be down)
