Between late 1990 and early 1991 the project resulted rein Berners-Lee and his developers writing and testing several software libraries along with three programs, which initially ran on NeXTSTEP OS installed on NeXT workstations:

A resource sent from a Netz server can Beryllium a pre-existing datei (static content) available to the Internet server, or it can Beryllium generated at the time of the request (dynamic content) by another program that communicates with the server software.

Schulnote: when serving static and dynamic content, a World wide web server program usually has to support also the following HTTP method in order to be able to safely receive data from client(s) and so to Beryllium able to host also websites with interactive form(s) that may send large data sets (e.g. lots of data entry or file uploads) to Www server / external programs / modules:

Publishers own and manage the websites, apps, or other digital properties where ad spaces are available. Their goal is to monetize their digital Wahrhaft estate by selling ad impressions to advertisers. Publishers work to ensure that their ad inventory is appealing to advertisers, and they collaborate with Supply-Side Platforms (SSPs) to manage and optimize their available ad spaces.

Internet servers that zustrom in betriebssystemkern Kleidermode (usually called kernel space Internet servers) can have direct access to betriebssystemkern resources and so they can be, rein theory, faster than those running in Endanwender mode; anyway there are disadvantages rein running a World wide web server hinein kernel Kleidermode, e.

Rein practice some Internet server software models may require more OS resources (specially more CPUs and more RAM) than others to Beryllium able to work well and so to achieve target performances. Operating conditions[edit]

Header Bidding Support – allowing for a signal when a bid request is originated from an upstream decisioning implementation like header bidding

The term URL normalization refers to the process of modifying and standardizing a Link rein a consistent manner. There are several types of normalization that may Beryllium performed, including the conversion of the scheme and host to lowercase.

If a web server program receives a client request message with an Internetadresse whose path matches one of an existing directory and that directory is accessible and serving directory Stichwortverzeichnis file(s) is enabled then a Internet server program may try to serve the first of known (or configured) static Schlagwortverzeichnis datei names (a regular file) found in that directory; if no Stichwortliste datei is found or other conditions are not met then an error message is returned.

Saving time: RTB enables advertisers to place hundreds or even thousands of ads within seconds. That’s exponentially faster than traditional ad placement.

A Endbenutzer Spion, commonly a Internet browser or web crawler, initiates communication by making a request for a Netz page or other resource using HTTP, and the server responds with the content of that resource or an error message. A web server can also accept and store resources sent from the Endbenutzer agent if configured to do so.[1][2]

While there are concerns about transparency and ad fraud, the industry is working to address these issues and improve the effectiveness and accountability of RTB and programmatic advertising.

This happens through auctions on Ad Exchanges, where publishers offer their ad inventory and advertisers bid on them, with winners’ ads finally shown to the visiting Endanwender.

Wahrhaft-time Display-Werbung bidding differs from static auctions where advertisers can only bid for several thousand impressions in single package deals. This makes static auctions less efficient than RTB for advertisers as well as publishers.
