Brotli is a data compression algorithm developed by Google and available since 2015. It was specially developed for compressing HTTP responses on the web and, compared to other algorithms such as Gzip or Deflate, offers a higher compression rate and thus faster data transmission. Compared to...

Brotli Compression is usually better than Gzip Compression because it can achieve a higher degree of compression, resulting in smaller file sizes. Brotli was specially developed for web compression and is therefore better adapted to the needs of HTTP/HTTPS than Gzip, which was originally intended...

The Tiny Memory Footprint refers to the low memory usage of an application or a system. It means that an application or system uses a minimal amount of memory and therefore works well on resource-constrained devices such as embedded systems, IoT devices or mobile devices. The Tiny Memory...

The LiteSpeed Server API is a programming interface (API) for the LiteSpeed web server. It allows to access and control various functions of the web server, e.g. managing virtual hosts, configuring security measures, monitoring system resources or running scripts and applications. The API is...

ESI:inline and ESI:include are two different directives in ESI, each used to embed dynamic content in a web application.ESI:include : This directive makes it possible to fetch dynamic content from another resource or server and embed it in the current page. The server loads the content...

HTTP/3 is a further development of the HTTP/2 protocol and has several advantages: Faster connection establishment: HTTP/3 uses the QUIC protocol as a transport protocol, which enables a faster connection establishment than TCP. This leads to shorter loading times. Better...

More and more web servers support the HTTP/3 protocol. Here are some of the most popular web servers that support HTTP/3:LiteSpeed Web Server: LiteSpeed was the first web server to support HTTP/3 in version 5.4. Apache: The latest release of Apache 2.4.x supports HTTP/3 through...

QUIC.cloud is a Content Delivery Network (CDN) built specifically for the QUIC protocol. Developed by LiteSpeed Technologies, it enables website owners to deliver their website content worldwide in a fast and secure manner.QUIC is a new transport protocol developed by Google and based on...

suEXEC is a mechanism used by some web servers, including Apache and LiteSpeed, to make running CGI scripts more secure. suEXEC allows CGI scripts to run under the user account of the file's owner, rather than the common web server user account that is normally used. This reduces the risk of...

Just-in-time configuration (JIT configuration) is a concept in which the configuration of an application or system is performed only when it is actually needed, rather than loaded in advance. This can improve performance and make systems easier to manage because only the necessary configurations...
