Introduction The OpenURL Framework for Context-Sensitive Services Standard [1] provides a means of describing a referenced resource along with a description of the context of the reference. Additionally it defines methods of transporting these descriptions between networked systems. It is anticipated that it will be used to request services pertaining to the referenced resource and appropriate for the requester. The OpenURL Framework is very general and has the potential to be used in many application domains and by many communities. Concrete instantiations of the various core components within the framework are defined within the OpenURL Registry [2]. The Registry is managed by a Maintenance Agency, as defined in Appendix A of the Standard. During the ballot and public review period of the Standard, the content of the Registry was static and had been pre-defined by the NISO AX Committee. There is also an experimental registry where components under development are held. It is possible to register further items. Initially there were two formats for ContextObject Representations

Tettamanzi, 2019 1 Unit 3 The Common Gateway Interface and Server-side Programming Andrea G. B. Tettamanzi, 2019 2 Agenda • The Common Gateway Interface • Server-Side Programming Andrea G. B. Tettamanzi, 2019 3 Introduction • An HTTP server is often used as a gateway to a different information system (legacy or not), for example – an existing body of documents – an existing database application • The Common Gateway Interface (CGI) is an agreement between HTTP server implementors about how to integrate such gateway scripts and programs • It was typically (but not exclusively) used in conjunction with HTML forms to build database applications • Nowadays largely superseded by dynamic Web content technologies such as PHP, ASP.NET, Java Servlets, and Node.js Andrea G. B. Tettamanzi, 2019 4 The Common Gateway Interface • The Common Gateway Interface (CGI) is a de facto standard protocol for Web servers to execute an external program that generates a Web page dynamically • The external program executes like a console application running on the same machine as the Web server (the host) • Such program is known as a CGI script or simply as a CGI Andrea G. B. Tettamanzi, 2019 5 How Does That Work? • Each time a client requests the URL corresponding to a CGI program, the server will execute it in real-time – E.g.: GET http://www.example.org/cgi-bin/add?x=2&y=2 • The output of the program will go more or less directly to the client • Strictly speaking, the “input” to the program is the HTTP request • Environment variables are used to pass data about the request from the server to the program – They are accessed by the script in a system-defined manner – Missing environment variable = NULL value – Character encoding is system-defined Andrea G.

    Internet Engineering Task Force (IETF) M. Nottingham Request for Comments: 7320 BCP: 190 July 2014 Updates: 3986 Category: Best Current Practice ISSN: 2070-1721 URI Design and Ownership Abstract Section 1.1.1 of RFC 3986 defines URI syntax as "a federated and extensible naming system wherein each scheme's specification may further restrict the syntax and semantics of identifiers using that scheme." In other words, the structure of a URI is defined by its scheme. While it is common for schemes to further delegate their substructure to the URI's owner, publishing independent standards that mandate particular forms of URI substructure is inappropriate, because that essentially usurps ownership. This document further describes this problematic practice and provides some acceptable alternatives for use in standards. Status of This Memo This memo documents an Internet Best Current Practice. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on BCPs is available in Section 2 of RFC 5741.

    Microsoft 70-480 MCSD Programming in HTML5 with JavaScript and CSS3 Microsoft 70-480 Dumps Available Here at: https://www.certification-questions.com/microsoft-exam/70-480-dumps.html Enrolling now you will get access to 317 questions in a unique set of 70- 480 dumps Question 1 You are developing a customer contact form that will be displayed on a page of a company's website. The page collects information about the customer. If a customer enters a value before submitting the form, it must be a valid email address. You need to ensure that the data validation requirement is met. What should you use? Options: A. <input name="email" type="url"/> B. <input name="email" type="text" required="required"/> C. <<input name="email" type="text"/> D. <input name="email" type="email"/> Answer: D Explanation: The <input type="email"> is used for input fields that should contain an e-mail address. Depending on browser support, the e-mail address can be automatically validated when submitted. Some smartphones recognize the email type, and adds ".com" to the keyboard to match email input. Example: <form> E-mail: <input type="email" name="email"/> </form> Reference: http://www.w3schools.com/html/html5_form_input_types.asp Question 2 https://www.certification-questions.com Microsoft 70-480 DRAG DROP You are developing a form that captures a user's email address by using HTML5 and jQuery. The form must capture the email address and return it as a query string parameter. The query string parameter must display the @ symbol that is used in the email address. You need to implement this functionality.

  • A Securityfocused HTTP Primer Basics Query Strings, Parameters
    2/19/2016 A Security­focused HTTP Primer Home Blog Study Essays Projects Services Podcast About A Security­focused HTTP Primer Home » Study » A Security­focused HTTP Primer What follows is a primer on the key security­oriented characteristics of the HTTP protocol. It’s a collection of a number of different sub­topics, explained in my own way, for the purpose of having a single reference point when needed. Basics Query Strings, Parameters, and Ampersands URL Encoding Authentication HTTP Requests Request Methods HTTP Responses Status / Response Codes HTTP Headers Proxies Cookies Basics Message­based You make a request, you get a response. Line­based Lines are quite significant in HTTP. Each header is on an individual line (each line ends with a <crlf>), and a blank line separates the header section from the optional body section. Stateless HTTP doesn’t have the concept of state built­in, which is why things like cookies are used to track users within and across sessions. Query Strings, Parameters, and Ampersands Query Strings (?) A query string is defined by using the question mark (?) character after the URL being requested, and it defines what is being sent to the web application for processing. They are typically used to pass the contents of HTML forms, and are encoded using name:value pairs. http://google.com/search?query=mysearch https://danielmiessler.com/study/http/ 1/9 2/19/2016 A Security­focused HTTP Primer Parameters (something=something) In the request above the parameter is the “query” value–presumably indicating it’s what’s being searched for.

  • REST Just Got Easy with SAS® and PROC HTTP Joseph Henry, SAS Institute Inc
    Paper SAS4426-2020 REST Just Got Easy with SAS® and PROC HTTP Joseph Henry, SAS Institute Inc. ABSTRACT Hypertext Transfer Protocol (HTTP) is the lifeblood of the web. It is used every time you upload a photo, refresh a web page, and in most every modern application you use today from your phone to your TV. A big reason why HTTP has become so ubiquitous with modern technology is because of a software architectural style known as Representational State Transfer (REST). REST has become the standard for interacting with independent systems across the web, which means that the consumption of REST APIs is, or is going to be, mandatory. The HTTP procedure in SAS® has enabled developers to use REST APIs simply and securely for many years now, but the demands of current systems keep increasing. PROC HTTP has been given quite a few updates to make using this great procedure even easier than it ever was before. INTRODUCTION The HTTP procedure has been a staple in SAS for many years for communicating with the web and Representational State Transfer (REST) APIs. Over the past few years, PROC HTTP has seen many updates that continue to increase its functionality and usability. SAS® Viya 3.5 continues this trend by introducing some new syntax to the procedure that makes many common tasks simpler as well as more accessible to newer SAS developers who might be used to other HTTP frameworks. The enhancements addressed in this paper are also available in SAS®9 as part of the second release of SAS 9.4M6.
