• Proxy-Server und WWW-Caching.
• Grundidee | Methode | Praxis an der Uni Zürich | Konfigurationen | Weitere Informationen | Technische Angaben | Proxy-FAQ | Zugriff auf geschützte Web-Bereiche der Universität Grundidee.
• Beim WWW-Caching werden Dokumente, die von einem Browser angefordert werden, nicht direkt beim ursprünglichen Server geholt, sondern via einem sog. Proxy-Server, der möglichst in der Nähe des Browsers installiert ist. Der Proxy-Server ist im Prinzip ein riesiges Reservoir an (kürzlich) angeforderten Dokumenten, welche vom Server in bezug auf ihre Aktualität verwaltet werden und allen Browsern zur Verfügung stehen, welche den Proxy-Server benutzen. Falls der Proxy-Server ein Dokument noch nicht kennt, oder die bekannte Version in bezug auf bestimmte Kriterien veraltet ist, so fordert er die aktuelle Version selbständig beim ursprünglichen Server an und schickt sie an den anfragenden Browser weiter. Damit kann der Netzwerkverkehr wesentlich reduziert werden, insbesondere dann, wenn viele Browser den gleichen Proxy-Server benutzen und/oder wenn dieselben Dokumente immer wieder von weit her geholt werden müssen (z. ... Der Betrieb eines Proxy-Servers ist somit nicht nur aus Kostengründen sehr vorteilhaft, er führt bei ´bekannten´ Dokumenten auch zu wesentlich kürzeren Antwortzeiten. ...
• Ein Proxy-Server hat im wesentlichen die folgenden Eigenschaften: .
• Gegenüber einem Browser (Client) sieht er aus wie ein WWW-Server. ...
• Gegenüber einem WWW-Server sieht er aus wie ein Client. ...
• Fordert ein Browser ein Dokument an, so prüft der Proxy-Server zuerst, ob er dieses Dokument bereits im Speicher hat. ... Ist es das, so schickt er es dem Browser direkt zurück, andernfalls schickt er dem ursprünglichen Server eine Anfrage, ob das Dokument in der Zwischenzeit modifiziert worden ist. ...
• Falls der Proxy-Server ein angefordertes Dokument noch nicht kennt, so gibt es mehrere Möglichkeiten:.
• Er fordert es direkt beim ursprünglichen Server an.

• Fundamentals of a Proxy Server.
• In the standard web server model a client requests a resource directly from a server and that server sends the resource directly back to the client. An alternate model incorporates a proxy server, an intermediate machine sitting between the server and the client(s), as illustrated by Figure 1. ...
• Figure 1: Proxy Setup .
• The proxy server model offers several several advantages. For instance, the proxy may be combined with a firewall to provide added security to a local area network (LAN). ... However, the proxy assures that access to the Internet by its clients is not hampered.
• Second, the proxy can act as a packet filter for incoming web traffic. Because all information first passes through the proxy before reaching the client, it can be manipulated in useful ways. For example, the proxy can read incoming HTTP (Hyper Text Transfer Protocol, the protocol used on the world wide web) packet requests and discard packets originating from a particular set of domains, such as pornographic sites. The proxy can also reduce ads being displayed on web pages by recognizing the image tag from known ad servers, and filtering the image out of the page before it reaches the client. ...
• Finally, the proxy can cache documents in much the same way as end-user browsers. The proxy may greatly decrease the access time for all clients, by caching the documents of many users. ...
• A possible means to this end is to utilize caching proxy servers that end users install and configure to communicate with a central database. This strategy is radically different than the traditional use for a proxy server.

This technique is used by some ISPs to reduce bandwidth usage without requiring their clients to configure their browser for proxy support. ...

• Spammers frequently seek out and make use of vulnerable third-party systems such as open mail relays and open proxy servers. The SMTP system, used to send email across the Internet, forwards mail from one server to another; mail servers that ISPs run commonly require some form of authentication that the user is a customer of that ISP. Open relays, however, do not properly check who is using the mail server and pass all mail to the destination address, making it quite a bit harder to track down spammers. ...
• An open relay is an MTA, or mail server, which is configured to pass along messages sent to it from any location, to any recipient. In the original SMTP mail architecture, this was the default behavior: a user could send mail to practically any mail server, which would pass it along towards the intended recipient's mail server. ...
• A proxy is a network service for making indirect connections to other network services. The client connects to the proxy and instructs it to connect to a server.

• A spammer can direct an open proxy to connect to a mail server, and send spam through it. The mail server logs a connection from the proxy -- not the spammer's own computer. ...

• Would it take any significant load off of the server if an external editing application were written (or maybe an extension for mozilla, or something along those lines), so that people could edit, press preview, edit, etc. until they get what they want, and then upload the edits, so that the previewing would not load down the server? (The only thing i can think of that it would need to check, to see if an article exists, to decide if the link should be red or not, wouldnt take up as much bandwidth as reloading the entire preview) I don't know how much of a load this would save, but it is a thought. ...

The book covers some general theory, and also has a lot of detailed stuff about the HTTP protocol and its interaction with proxy servers. ...
• This book is written by the guy who practically invented the HTTP proxy server. ... Unfortunately, while the book would be fantastic (5 stars) for any proxy administrator--overkill, perhaps--it isn't quite thorough enough for the developers. Right now I'm struggling with creating a proxy server in Java and the road block I've come across is with SSL support.
