Backend development also stylized as back-end or back end development is the skill that powers the web. Yet it does it modestly, without fanfare—allowing people to browse their favorite sites without even knowing about all the work put in by the backend developer or team. So to help dispel this mystery…what is backend development? How do backend technologies work? What are some back end developer languages?

The "separate sites" approach to mobile Web development involves creating different sites for mobile and desktop Web users. This approach has positive and negative aspects. The first option is the most popular by far: use user-agent detection to route users on phones to a separate mobile site, typically at m. In a nutshell, this technique uses server-side logic to solve all three goals of mobile web development at once — if the user's browser looks like it's on a phone, you serve them mobile content, formatted for their phone and optimized for speed. Conceptually simple, this is the easiest option to add to an existing site, especially if you are using a CMS or Web application that supports templates. Since only the mobile-specific content, styles, and scripts are sent to mobile users, this method also provides for the best performance out of any of the other options presented here. Finally, it also allows for completely different user experiences on desktop and mobile — they're two different sites, after all! Unfortunately, this approach is not without its drawbacks.
Now, what we have to do as our first task is declare the type document that for HTML5 is indicated in the following way:.

Cross Site Scripting (XSS)
You may see many websites having a desktop version and also a simplified mobile version of the same website to make it simpler for mobile internet users. But to do it you must have to detect a mobile device. Detecting a mobile device from the server side is the best as it will not load unnecessary content and really make a website faster by loading only the content that you want to show on mobile device. Although you can use CSS media query, it will not prevent mobile devices from loading content that you want only for computers or desktop.

Cross-Site Scripting XSS attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user. Flaws that allow these attacks to succeed are quite widespread and occur anywhere a web application uses input from a user within the output it generates without validating or encoding it. An attacker can use XSS to send a malicious script to an unsuspecting user. Because it thinks the script came from a trusted source, the malicious script can access any cookies, session tokens, or other sensitive information retained by the browser and used with that site.

Unfortunately, the XMLHttpRequest object doesn't allow calls made in one domain to a web service in another. The article surveys the current, somewhat unsatisfactory, solutions and then assesses future directions. One of the current vogues in web applications is the creation of mashups. The APIs allow the developer to select content through a series of filters such as location, date, user id, or membership of a particular group. The APIs are almost always thinly disguised wrappers for a web service. However, there is one big hitch to this theory. This is sensible given that if you called a script in one place and it, in turn, called a script on another server, it could leave an applicationopen to all sorts of malicious scripts, hacks and exploits.
