Many of the Ruby on Rails Ajax-enabled helper methods used to work by using Prototype to perform an Ajax request in older versions of Rails. In most cases Javascript code is returned by the server to be executed by the browser, unlike the usual case where Ajax is used to retrieve data in XML or JSON format.
A de facto standard for identifying the original host requested by the client in the Host HTTP request header, since the host name and/or port of the reverse proxy (load balancer) may differ from the origin server handling the request. Superseded by Forwarded header. X-Forwarded-Host: en.wikipedia.org:8080. X-Forwarded-Host: en.wikipedia.org
A web page may freely embed cross-origin images, stylesheets, scripts, iframes, and videos. Certain "cross-domain" requests, notably Ajax requests, are forbidden by default by the same-origin security policy. CORS defines a way in which a browser and server can interact to determine whether it is safe to allow the cross-origin request. [1]
A query string is a part of a uniform resource locator (URL) that assigns values to specified parameters. A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.
XMLHttpRequest data is subject to this security policy, but sometimes web developers want to intentionally circumvent its restrictions. This is sometimes due to the legitimate use of subdomains as, for example, making an XMLHttpRequest from a page created by foo.example.com for information from bar.example.com will normally fail.
Verifying that the request's headers contain X-Requested-With (used by Ruby on Rails before v2.0 and Django before v1.2.5), or checking the HTTP Referer header and/or HTTP Origin header. [ 31 ] Checking the HTTP Referer header to see if the request is coming from an authorized page is commonly used for embedded network devices because it does ...
A server implements an HSTS policy by supplying a header over an HTTPS connection (HSTS headers over HTTP are ignored). [1] For example, a server could send a header such that future requests to the domain for the next year (max-age is specified in seconds; 31,536,000 is equal to one non-leap year) use only HTTPS: Strict-Transport-Security: max-age=31536000.
In this circumstance, the Location header should be sent with an HTTP status code of 3xx. It is passed as part of the response by a web server when the requested URI has: Moved temporarily; Moved permanently; or; Processed a request, e.g. a POSTed form, and is providing the result of that request at a different URI
