In some cases, such as the Googlebot, Web crawling is done on all text contained inside the hypertext content, tags, or text.

Googlebot is the search bot software used by Google, which collects documents from the web to build a searchable index for the Google search engine.

If a webmaster wishes to restrict the information on their site available to a Googlebot, or another well-behaved spider, they can do so with the appropriate directives in a robots. txt file, or by adding the meta tag < code >< nowiki >< meta name =" Googlebot " content =" nofollow " /></ nowiki ></ code > to the web page.

There is increasing evidence Googlebot can execute javascript and parse content generated by Ajax calls as well.

Googlebot discovers pages by harvesting all of the links on every page it finds.

Some crawlers like Googlebot and Slurp recognize strings containing "*", while MSNbot and Teoma interpret it in different ways.

* Googlebot is described in some detail, but the reference is only about an early version of its architecture, which was based in C ++ and Python.

Currently, Googlebot follows HREF links and SRC links.

A problem which webmasters have often noted with the Googlebot is that it takes up an enormous amount of bandwidth.

The Semantic Web, as originally envisioned, is a system that enables machines to " understand " and respond to complex human requests based on their meaning.

In some cases, crawlers may be accidentally trapped in a crawler trap or they may be overloading a Web server with requests, and the owner needs to stop the crawler.

The system also handles requests for " subscriptions " to Web pages that must be monitored: when the pages change, they must be downloaded by the crawler and the subscriber must be notified.

When a Load Balancer terminates the SSL connections the requests are converted from HTTPS to HTTP in the Load Balancer before being passed to the Web Server.

Also called the " Show Michigan the Money Project ”, this initiative uses press releases and Freedom of Information Act requests to encourage governments to meet their “ obligation to disclose their actions and expenditures ” and to “ make their checkbook spending directly available to the public .“ The MichiganTransparency. org Web site contains links to the Center ’ s own school finance database and to various government sites disclosing spending details, and other information sources.

Within a few weeks the Web site was no longer responding to requests and has even dropped from DNS.

Web sites of manufacturers and large suppliers do not always include them even if the information is obtainable from retailers but written or telephone requests for paper copies will usually be responded to favourably.

* Outreach – sponsor conferences, educational programs, and exhibits ; operate an information clearinghouse to answer inquiries and requests for information ; provide a Web site and printed publications ; and hold town meetings at selected locations in the United States.

The Open Geospatial Consortium Web Feature Service Interface Standard ( WFS ) provides an interface allowing requests for geographical features across the web using platform-independent calls.

* A reverse cache sits in front of one or more Web servers and web applications, accelerating requests from the Internet.

Like the Windows Client, the Web Client connects to and requests forms and data from and instance of the Dataphor Server.

* Internet Explorer version 6. 0. 2900. 2180. xpsp_sp2_rtm requests " wpad. da " instead of " wpad. dat " from the Web server.

* Library for WWW in Perl, a set of Perl modules that allow requests to be sent to the World Wide Web

The goal of SPML is to allow organizations to securely and quickly set up user interfaces for Web services and applications, by letting enterprise platforms such as Web portals, application servers, and service centers generate provisioning requests within and across organizations.

The scripting also allows use of remote scripting, a technique by which the DHTML page requests additional information from a server, using a hidden Frame, XMLHttpRequests, or a Web service.

When an agent ( such as a Web browser ) requests a resource from a Web server, the agent sends the URI to the server, but does not send the fragment.

The first component to allow client-side scripts to issue HTTP requests ( XMLHTTP ) was originally written by the Outlook Web Access team.

Google Web Accelerator sent requests for web pages, except for secure web pages ( HTTPS ), to Google, which logged these requests.

LWP ( for " Library for WWW in Perl ", also called libwww-perl ) is a set of Perl modules that allow requests to be sent to the World Wide Web.

This allows WCF service endpoints to service requests from AJAX-powered Web pages which only accept JSON.

An academic paper from 1997 introduced the term " consistent hashing " as a way of distributing requests among a changing population of Web servers.

Clients therefore initiate communication sessions with servers which await incoming requests.

* fwd ( forward server ): Forwards requests to other servers, used by fifo and symlink servers.

An LDAP server may return referrals to other servers for requests that it cannot fulfill itself.

A typical example of a file transfer that does not use the P2P model is the File Transfer Protocol ( FTP ) service in which the client and server programs are distinct: the clients initiate the transfer, and the servers satisfy these requests.

Modern networks use central coordinating servers and directed search requests.

Many sites ' servers thought the requests were from a virus or spyware trying to cause a Denial of Service attack, warning users that their queries looked like " automated requests from a computer virus or spyware application ".

* Proxy server, acts as an intermediary for requests from clients seeking resources from other servers

The load balancer forwards requests to one of the " backend " servers, which usually replies to the load balancer.

If this information is stored locally on one backend server, then subsequent requests going to different backend servers would not be able to find it.

This feature utilizes HTTP / 1. 1 to consolidate multiple HTTP requests from multiple clients into a single TCP socket to the back-end servers.

* HTTP caching: the load balancer can store static content so that some requests can be handled without contacting the web servers.

* Content-aware switching: most load balancers can send requests to different servers based on the URL being requested, assuming the request is not encrypted ( HTTP ) or if it is encrypted ( via HTTPS ) that the HTTPS request is terminated ( decrypted ) at the load balancer.

In computer networks, a proxy server is a server ( a computer system or an application ) that acts as an intermediary for requests from clients seeking resources from other servers.

A reverse proxy taking requests from the Internet and forwarding them to servers in an internal network.

Normally they act as servers for timing requests from Stratum 2 servers via NTP.

: These are computers that send NTP requests to Stratum 1 servers.

Stratum 2 computers normally act as servers for Stratum 3 NTP requests.

It directly answers requests for records in the root zone and answers other requests returning a list of the designated authoritative name servers for the appropriate top-level domain ( TLD ).

IIS dropped from the second most popular position at the end of 2011, where during October it previously held 14 % of servers and responded to 12 % of total requests.

For example, this may be used as the method of distributing incoming requests to a number of processors, worker threads, or servers.

On the reception side, the content servers can typically receive service requests both from WAP and normal HTTP browsers, so delivery via the web is simple.
