Summary Warning The session modules make use of HTTP cookies, and as such can fall victim to Cross Site Scripting attacks, or expose potentially private information to clients. Please ensure that the relevant risks have been taken into account before enabling the session functionality on your server. This submodule of mod_session provides support for the storage of user sessions on the remote browser within HTTP cookies. Using cookies to store a session removes the need for the server or a group of servers to store the session locally, or collaborate to share a session, and can be useful for high traffic environments where a server based session might be too resource intensive.
A robots.txt file restricts access to your site by search engine robots that crawl the web. These bots are automated, and before they access pages of a site, they check to see if a robots.txt file exists that prevents them from accessing certain pages. (All respectable robots will respect the directives in a robots.txt file, although some may interpret them differently. However, a robots.txt is not enforceable, and some spammers and other troublemakers may ignore it. For this reason, we recommend password protecting confidential information.)
Support module for Common Gateway Interface (CGI) scripts. This module defines a number of utilities for use by CGI scripts written in Python. 20.2.1. Introduction A CGI script is invoked by an HTTP server, usually to process user input submitted through an HTML <FORM> or <ISINDEX> element.
To get to the Menu on Google Chrome browser, click on the “Wrench” icon on the top right-hand corner. From here you can access certain browser features. However, there are several features that are not available from the Menu, which you can access only using the chrome:// commands. Some of the features are available under both Menu and chrome:// commands.
A data packet on an Ethernet link is called an Ethernet frame . A frame begins with preamble and start frame delimiter. Following which, each Ethernet frame continues with an Ethernet header featuring destination and source MAC addresses . The middle section of the frame is payload data including any headers for other protocols (e.g. Internet Protocol ) carried in the frame.
Hacking Apache HTTP Server at Yahoo! , Thursday, July 27, 2006 (OSCON 2006) Slides in HTML | PDF | PPT Since 1996, Yahoo has been running Apache HTTP Server on thousands of servers and serving billions of requests a day. This session reveals the secrets of how Yahoo gets maximum performance out of minimal hardware by tweaking configuration directives and hacking the source code. Radwin will cover topics such as reducing bandwidth costs, extensible logfile format and rotation schemes, dumping core gracefully, and how to avoid the dreaded MaxClients, Max/MinSpareServers, StartServers configuration nightmare.

It is a very useful diagnostic tool for SSL servers. In addition to the options below the s_client utility also supports the common and client only options documented in the in the SSL_CONF_cmd(3) manual page. -connect host:port
The user data directory contains data specific to a given user. Some examples of this type of data are: history, bookmarks, and cookies. Note that in Windows, the profile name is included in the directory hierarchy. Default Location
Je réponds à ma propre question ici, puisque nous n'avons reçu aucune réponse des développeurs. Chrome est maintenant à la version 3, et il n'y a toujours aucun moyen de modifier le settings.This cache semble être le cas pour les autres produits Google ainsi, puisque je n'ai trouvé aucun moyen pour changer d'emplacement mémoire cache dans Google Earth soit. Depuis que j'ai posté ma question initiale, j'ai été en utilisant des liens symboliques pour contourner le problème.
UTF-8 ( UCS Transformation Format—8-bit [ 1 ] ) is a variable-width encoding that can represent every character in the Unicode character set. It was designed for backward compatibility with ASCII and to avoid the complications of endianness and byte order marks in UTF-16 and UTF-32 . UTF-8 has become the dominant character encoding for the World-Wide Web , accounting for more than half of all Web pages. [ 2 ] [ 3 ] [ 4 ] The Internet Engineering Task Force (IETF) requires all Internet protocols to identify the encoding used for character data, and the supported character encodings must include UTF-8. [ 5 ] The Internet Mail Consortium (IMC) recommends that all e-mail programs be able to display and create mail using UTF-8. [ 6 ] UTF-8 is also increasingly being used as the default character encoding in operating systems , programming languages , APIs , and software applications . [ citation needed ]
This page was getting big - we're talking big. So we split the mobile things onto a separate page. We started these pages with four strings because we had never seen a comprehensive list anywhere. Nominally RFC 1945 and RFC 2068 define them ( get RFCs ) but only as an afterthought (the RFCs define HTTP 1.0 and 1.1). Browser IDs, more correctly User Agent IDs, appear, among other places, as the environmental variable HTTP_USER_AGENT in Apache. You need this information to make the fewest checks possible for the browser environment or to optimise the display or ... to know who and what is crawling around your site.

HTTP header fields are components of the message header of requests and responses in the Hypertext Transfer Protocol (HTTP). They define the operating parameters of an HTTP transaction. The header fields are transmitted after the request or response line, the first line of a message. Header fields are colon-separated name-value pairs in clear-text string format, terminated by a carriage return (CR) and line feed (LF) character sequence.
