<h2>Details</h2>
|
|
|
|
YaCy supports the following features:<br>
|
|
<table border="0" cellspacing="1" cellpadding="3" width="100%">
|
|
|
|
</td></tr><tr><td valign="top"><b>Built-in Indexing and Search Engine</b></td><td>
|
|
The proxy 'scrapes' the content that it passes and creates an index that can be shared between every YACY Proxy daemons.
|
|
You can use the indexing feature for intranet indexing:
|
|
you instantly have a search service at hand to index all intranet-served web pages.
|
|
You don't need to set up a separated search service. And the used <a href="http://www.anomic.de/AnomicPlasma/index.html">PLASMA</a>
|
|
indexing is not a naive quick-hack but an <a href="Technology.html">properly engineered and extremely fast algorithm</a>;
|
|
it is capable of indexing a nearly unlimited number of pages, without slowing down the search process.
|
|
|
|
</td></tr><tr><td valign="top"><b>p2p-Based Global Search Engine</b></td><td>
|
|
The proxy contains an index-sharing p2p-based algorithm which creates a global distributed search engine.
|
|
This spawns a world-wide global search index.
|
|
The current release is a minimum implementation of this concept and shall prove it's functionality.
|
|
|
|
</td></tr><tr><td valign="top"><b>Caching HTTP and transparent HTTPS Proxy</b></td><td>
|
|
With optional pre-fetching. HTTP 1.1 with GET/HEAD/POST/CONNECT is supported. This is sufficient for nearly all public web pages.
|
|
HTTP headers are transparently forwarded. HTTPS connections through target port 443 are transparently forwarded, non-443 connections are suppressed to enhance security. Both (HTTP and HTTPS) proxies share the same proxy port, which is by default port 8080.
|
|
|
|
</td></tr><tr><td valign="top"><b>Privacy</b></td><td>
|
|
The proxy protects your privacy, even with index sharing switched on. Please see the
|
|
<a href="Technology.html">privacy secion in the documentation.</a>;
|
|
|
|
</td></tr><tr><td valign="top"><b>Security</b></td><td>
|
|
The proxy can block unwanted access by setting IP filters and http passwords.
|
|
You can also enhance security by inspecting the source code, which is completely included.
|
|
Check the code and re-build your own proxy.
|
|
|
|
</td></tr><tr><td valign="top"><b>Web/HTTP server</b></td><td>
|
|
The built-in HTTP server is the interface to the local and global search service;
|
|
the server may not only be used to administrate the proxy, but also to serve as an intranet/internet web server.
|
|
|
|
</td></tr><tr><td valign="top"><b>Ideal Internet Cafe Proxy Solution</b></td><td>
|
|
Every Internet Cafe needs a caching proxy instead only a NAT to route the cafe's client traffic from the internet to maximize bandwidth.
|
|
This can only be done using a <i>caching</i> proxy. This is naturally provided by the YACY Proxy. Future versions may also include
|
|
billing support functions.
|
|
|
|
</td></tr><tr><td valign="top"><b>Terminal-Based</b></td><td>
|
|
the proxy does not need to have a window-based environment and can run on a screen-less router; therefore you may run the proxy on your already existing servers, whatever they are since YACY Proxy is written in java and will run also on your platform.
|
|
|
|
</td></tr><tr><td valign="top"><b>Open-Source</b></td><td>
|
|
This is a simple necessity for an application that implements a server.
|
|
Don't use any other server software that does not come with the source code.
|
|
<a href="Volunteers.html">Volunteers</a> to extent the proxy are welcome!
|
|
If you think you have a great idea how to extend/enhance/fix the proxy, please let me know.
|
|
|
|
</td></tr><tr><td valign="top"><b>Easy Installation</b></td><td>
|
|
You just need to decompress the release containter with your favourite decompressor (zip, rar, sit, tar etc. will do)
|
|
and double-click the application wrapper for your OS. No restart necessary.
|
|
Just double-click the application wrapper.
|
|
|
|
<tr><td width="30%" valign="top"><b>Licence Model</b></td><td width="70%">
