1. Propagation, Caching and Replication on the Web
- www.w3.org
- Propagation, Caching and Replication on the Web .
- As the Web has grown and continues to grow at exponential rates, the demand for efficient caching and replication has become a clear MUST in the Web architecture. However, it has also become clear that caching and replication affects all layers of the Internet - not only the application layer where HTTP and the Web normally belongs. ...
- Now it is time for technologies such as multicast, directory services, and caching and replication to come together and to collaborate in order to move the Web forward. ...
- Check out our list of interesting papers related to propagation, caching and replication. ...
- 1 functionality including caching and persistent connections. ...
- There are not that many mailing lists dedicated to discussing caching and replication. ...
- IETF has traditionally been deeply involved in propagation and caching of information as this is an important part of the Internet architecture. There are many examples of caching and propagation from DNS, directory services, and at the lower level of routing protocols. ... Web Caching Projects .

4. WCW-7: Seventh International Workshop on Web Content Caching and Distribution
- 2002.iwcw.org
- Web Content Caching and Distribution (WCW) .
- Since 1996, this workshop has served as the premier forum for researchers and industry technologists to exchange research results and perspectives on future directions in Internet content caching and content delivery. The first four Web Caching Workshops (WCW) focused on Web cache software and caching networks for static Web content.
5. Web traffic characterization: an assessment of the impact of caching documents from NCSA's web server
- www.ncsa.uiuc.edu
- Web traffic characterization: an assessment of the impact of caching documents from NCSA's web server .
- The wide geographic diversity of query sources and popularity of a relatively small portion of the web server file set present a strong case for deployment of geographically distributed caching mechanisms to improve server and network efficiency. ...
- We analyze the impact of caching the results of queries within the geographic zone from which the request was sourced, in terms of reduction of transactions with and bandwidth volume from the main server. ...
- We also discuss other issues that caching inevitably poses, such as how to redirect queries initially destined for a central server to a preferred cache site. ...

6. Cashing in on Caching
- www.ariadne.ac.uk
- Cashing in on Caching.
- Jon Knight and Martin Hamilton describe Caching, possibly the most crucial tool available to frequent Web users, and point out why Libraries should be aware of it. ...
- One technique which helps both improve responsiveness for WWW end users and also reduces network loading is caching. This article explains how WWW caching works, why librarians should be looking at it and briefly outlines the software and services that are currently available. ...
- What is Caching?.
- The basic idea behind caching is to keep copies of the things which have recently been looked at. Caching techniques are used at all levels of modern computer systems, but are a comparative late-comer to the Web. On the Web, caching typically involves the browser itself remembering the objects which were returned when URLs were looked up, by storing them on disk and in memory, and possibly sending its requests via a cache server rather than using them to directly access the remote server. ...
- The basic model of caching works well for static documents that never change. ... The presence of these types of resources has resulted in the development of more sophisticated caching policies that allow browsers and proxy servers to determine how long local copies of cached resources should be kept. ... The only noticeable effect to the end users should be that access times to most, but not all, resources are dramatically reduced by the use of caching. ...
- We should note in passing that Web page developers may defeat most caching schemes by making extensive use of uncachable resources such as CGI programs. ... If there is a bottom line, it's that the Web is evolving towards an architecture which will be totally dependent upon caching, and you cannot count on being able to gather truly accurate statistics. ...
- To really work effectively, caching should ideally take place over a relatively large population of users. ...
- Why should libraries need to know about caching?.
- There are a number of reasons why libraries with Internet access and public Web browsers should be interested in caching. ...

10. Cyberspace Law Institute
- www.cli.org
- That is, even if one believed that caching involves a prima facie infringement of the Web page owner's exclusive right to produce "copies" of the Web page in question, it seems reasonable and appropriate to describe basic forms of caching (such as those described in Appendix A) as impliedly authorized by the content provider, inasmuch as they merely facilitate access to, and utilization of, the information placed on the Web by the content provider -- to assert, in other words, that the context in which these transactions take place, and the "custom and usage" of the relevant community, provide sufficient authorization for basic caching transactions.
- Difficulties arise, however, in trying to distinguish privileged caching of this kind from acts of copying less clearly authorized, and in determining whether -- or to what extent -- the owner of a web page may expressly override such implied authorization and impose restrictions and conditions on such caching. ... , transitory storage in RAM, is likely to prove too narrow a privilege, because many web browsers (including the current industry standard, Netscape) store copies of cached material even after the session is terminated and the browser is exited (so that the next time the browser is run, the cached files are available to it), and we see no principled reason to distinguish between caching procedures on this basis. ... NOTE 6 Ideally, the uncertainty regarding the respective rights of web page owners and those engaged in caching would be resolved by agreement. ... The problems stem from the fact that caching results from automated algorithms and occurs at a scale that renders attention to idiosyncratic terms and conditions infeasible. ...
- In short, the ideal situation would be one in which the owner of a web page is permitted to impose restrictions on caching to the extent, but only to the extent, that such restrictions are capable of being communicated and implemented by means of the standard technical protocols that control automatic caching algorithms. ... Web page owners may well have an interest in conditioning caching, for example, on the ability to receive information regarding the number of hits to the cached page, or on the continued ability to implement password protections or to charge fees, or on the receipt of demographic information regarding users of the page. We are conducting inquiries to determine the extent of other means available to web page owners to use html to embed instructions regarding caching in web pages, which instructions might then be carried out by servers using the http protocol. ...
- Caching, for this purpose, is defined to mean the copying of a web page, made incidental to the first access to the page, and storage of that copy for the purpose of speeding subsequent access; a brief overview of caching usage is set forth in Appendix A.
- Or caching might be used to circumvent any system on Content Server that records the number of "hits" from Consumers. ...
- Appendix A: Caching on the World Wide Web.
- The service provider's World Wide Web access system may provide for the caching of material retrieved through the web on the service provider's host, so that if another subscriber wish to retrieve the same material, the second subscriber could do so directly from the service provider's host computer, without the host having to go out and fetch the material again across the Internet.

12. HTTP/1.1: Caching in HTTP
- www.w3.org
- 13 Caching in HTTP.
- 1 protocol includes a number of elements intended to make caching work as well as possible. Because these elements are inextricable from other aspects of the protocol, and because they interact with each other, it is useful to describe the basic caching design of HTTP separately from the detailed descriptions of methods, headers, response codes, etc. ...
- Caching would be useless if it did not significantly improve performance. The goal of caching in HTTP/1. ...
- These directives typically override the default caching algorithms. ...
- Many user agents make it possible for users to override the basic caching mechanisms. ... The user agent SHOULD NOT default to either non-transparent behavior, or behavior that results in abnormally ineffective caching, but MAY be explicitly configured to do so by an explicit action of the user. ...
- If the user has overridden the basic caching mechanisms, the user agent SHOULD explicitly indicate to the user whenever this results in the display of information that might not meet the server's transparency requirements (in particular, if the displayed entity is known to be stale). ...
- If the user has overridden the caching mechanisms in a way that would abnormally reduce the effectiveness of caches, the user agent SHOULD continually indicate this state to the user (for example, by a display of a picture of currency in flames) so that the user does not inadvertently consume excess resources or suffer from excessive latency. ...
- HTTP caching works best when caches can entirely avoid making requests to the origin server. ...
- An expiration time cannot be used to force a user agent to refresh its display or reload a resource; its semantics apply only to caching mechanisms, and such mechanisms need only check a resource's expiration status when a new request for that resource is initiated. ...
- 3) appears in the response, and the response does not include other restrictions on caching, the cache MAY compute a freshness lifetime using a heuristic. ...
- However, weak validators allow for more efficient caching of equivalent objects; for example, a hit counter on a site is probably good enough if it is updated every few days or weeks, and any value during that period is likely "good enough" to be equivalent. ...
- Note: in order to provide semantically transparent caching, an origin server must avoid reusing a specific strong entity tag value for two different entities, or reusing a specific weak entity tag value for two semantically different entities. ...
- 1 caching proxy, upon receiving a conditional request that includes both a Last-Modified date and one or more entity tags as cache validators, MUST NOT return a locally cached response to the client unless that cached response is consistent with all of the conditional header fields in the request. ...
