What is Iframe's cross domain?
Inserted Cross Domain (Iframe) is a type of web technology that can be used to insert a small part of one site into a larger page of the "parent" hosted in another domain. On the website you can easily place content containing content from an external site, such as a social network sharing service or video sharing video to add new features or increase interactivity. This practice is supported and encouraged by many of the most popular social networks and search engines that benefit from increased operation and exposure by allowing smaller sites to access their services. Despite their popularity, Iframes suffer from constraints caused by security restrictions and incompatibility that can cause problems for websites developers. Iframe and its superior website are independent of each other, which means they are loading on the browser and can be updated individually. Using inline images on the web has evolved since they were first introduced at the end of the 90's; Originally meLy be used with the content hosted on the same server or domain, but now they are commonly used to load external content from another site. This is known as the Iframe Cross Domain.
Iframe Cross Domain has become a popular way for website developers to add multimedia, interactive content or social network features with minimal efforts. In many cases, adding these elements is as simple as copying and inserting HTML code from an external website. Video sharing websites, social network services, and search engines routinely offer this feature that supports greater use of their products. For example, the news site could use this approach to add a small section of social networks that show users that friends liked a specific article or story. The Iframe Cross Domain can also be used to add widgets or other types of functionalityOn the site without extensive programming.
Technical limits, safety restrictions and incompatibility problems can reduce the strength of the Iframe Cross domain and cause headaches for developers. Iframe communication between different domains is blocked by web browsers for security reasons, making it impossible to access or change the content inside the externally hosted Iframe without a time -consuming solution. HTML 5, continuing to upgrade key parts of web technology technology, involves providing communication between Iframe Cross Domain, but this is only a practical solution if the vast majority of users visiting the web has a web browser that supports this part of the HTML 5 specifications.
