UTF-8 is the default encoding for Web documents since HTML4 in 1999 and the only practical way to make modern Web pages. The http-equiv attribute in the meta tag is used to define HTTP header equivalents, and it has specific valid values, such as “content-type”, “expires”, “refresh”, and “content-security-policy”. This metadata is typically specified using attributes like charset, content, http-equiv, itemprop, name, and property. To resolve this issue, you must remove or correct the http-equiv attribute value.
- Spark creativity and collaboration in any learning environment with a variety of Microsoft 365 apps and free templates to choose from.
- It went stable in September 2010, on the first birthday of the project.
- Create equitable learning environments that help students develop knowledge with familiar apps essential to both academic and future career success.
- HTML lets you specify metadata – additional important information about a document in a variety of ways.
You can share and edit and store and read and recover and rely on that document in many contexts. In either app, there is a menu at the bottom of the document window where you specify the document encoding and you can easily choose “UTF-8 no BOM”. And of course you can set that as the default for new documents in Preferences. Microsoft says the Racine County data center would be the first of several facilities, located in multiple states, in the company’s latest initiative to compete with other technology companies like Facebook’s parent company Meta on artificial intelligence.
HTML Tags
The Microsoft 365 Copilot app brings together your favorite apps in one intuitive platform that keeps your data secure with enterprise data protection. Follow along with the video below to see how to install our site as a web app on your home screen. Using these methods, you ensure compliance with HTML5 standards by handling HTTP headers correctly. The reason is that not many email readers use HTML5, so it’s always better use old HTML styles. Finally, consider saving your documents with Unix line endings, not legacy DOS or (classic) Mac line endings, which don’t help and may hurt, especially down the line as we get further and further from those legacy systems.
Create a Server
If controlling cache behavior is necessary, it should be handled via server configuration rather than within the HTML document using a meta tag. The http-equiv attribute is used in web pages to simulate an HTTP response header. While HTTP response headers can be set from the server, not everyone has access to the server configuration, so an alternative is using to define settings that would otherwise require setting an HTTP response header.
Code Game
Microsoft is finishing construction on its first Racine County data center, which is to be completed in early 2026. The company says it will hire more than 400 employees to work at the first data center and once the second data center is open, the total number of employees plans to be nearly 800 for both facilities. Explore learning tools to collaborate on projects together and independently, all in one place. Anyone in your organization can quickly create documents, presentations, and worksheets within a single, unified app experience. Tutorials Point is a leading Ed Tech company striving to provide the best learning material on technical and non-technical subjects. This tag is an empty element and so does not have a closing tag but it carries information within its attributes.
Example of Setting Expires at Server Level:
Fortunately, developers can leverage meta HTML tags to control caching behaviour, ensuring users receive the latest content promptly. This article explores the significance of browser caching and demonstrates the use of meta HTML tags to enhance web speed. However, cacheing headers are unreliable in meta elements; for one, any web proxies between the site and the user will completely ignore them. You should always use a real HTTP header for headers such as Cache-Control and Pragma.
You might configure caching on your web server (e.g., Apache, Nginx) to handle Cache-Control instead of using an invalid meta tag in your HTML. On the server, the base tag is unnecessary, but when opened from local storage, the base tag enables the page to work as if it is on the server, with all the assets in place and so on, no broken links. You can use UTF-8 or utf-8, however UTF-8 is clearer, more readable, more accurate. Caching headers are unreliable in meta elements; for one,any web proxies between the site and the user will completely ignorethem. You should always use a real HTTP header for headers such asCache-Control and Pragma. The list is just examples of different techniques, it’s not for directinsertion.
UTF-8 Reference
- On Sept. 15, Midwest Environmental Advocates, on behalf of Milwaukee Riverkeepers, filed a lawsuit against the city of Racine, which provides water to Mount Pleasant, for documents related to the Microsoft development.
- Finally, consider saving your documents with Unix line endings, not legacy DOS or (classic) Mac line endings, which don’t help and may hurt, especially down the line as we get further and further from those legacy systems.
- The use of Pragma is obsolete and was mainly supported in older HTML specifications for compatibility with HTTP/1.0 proxies.
- The http-equiv attribute is used in web pages to simulate an HTTP response header.
- This will configure Apache to serve your files declaring UTF-8 encoding in the Content-Type response header, but your files must be saved in UTF-8 (without BOM) to begin with.
The use of Pragma is obsolete and was mainly supported in older HTML specifications for compatibility with HTTP/1.0 proxies. The recommended way to control caching in modern web development is through appropriate HTTP headers sent from the server. Also, there is absolutely no reason at all to use any value other than UTF-8 in the meta charset attribute or page header.

Smith addressed the water concerns saying, “Lake Michigan has nothing to fear from our data center” and added the company has built data centers in places like Phoenix, Qatar and Abu Dhabi. HTML lets you specify metadata – additional important information about a document in a variety of ways. The META elements can be used to include name/value pairs describing properties of the HTML document, such as author, expiry date, a list of keywords, document author etc. The W3C HTML Validator issue you’re encountering indicates that the value specified for the http-equiv attribute in a tag is not valid. This often happens due to incorrect formatting, spelling errors, or extraneous characters in the attribute value. An HTML document with valid HTML5, UTF-8 encoding, and Unix line endings is a job well done.
Is there a tag to turn off caching in all browsers? duplicate
The new project includes construction of the facility and technology infrastructure, according to a company announcement on Sept. 18. That is why we put the meta charset tag at the top, right after the head tag, before anything else, even the title. Microsoft and We Energies have proposed a special rate specific for data centers to minimize impact on local residents. Separate from the lawsuit, Clean Wisconsin conducted an analysis of the power used by data centers in Mount Pleasant and Port Washington stating the facilities could use more electricity than all the houses in Wisconsin.
But if your Webserver serves the encoding in the HTTP header,which is recommended, both meta tags are needless. The best practice is to set Cache-Control and Pragma headers server-side, not in HTML. Using a tag for something like content-type and encoding is highlyironic, since without knowing those things, cryptopia withdrawal time you couldn’t parse the fileto get the value of the meta tag. This will configure Apache to serve your files declaring UTF-8 encoding in the Content-Type response header, but your files must be saved in UTF-8 (without BOM) to begin with. In the fast-paced internet era, delivering up-to-date content to users is crucial. Browser caching, while speeding up website loading, poses challenges in serving recent updates.
