Addressing Mixed Content Errors on Sites Accessed via HTTPS

Molly Wojcik | October 24, 2018 | Performance

Mixed content takes place whenever initial HTML is loaded over a secure HTTPS connection while other resources (e.g. scripts, images, videos) are loaded over an unsecure HTTP connection. Due to the fact that the initial request was secure over HTTPS, and both HTTP and HTTPS need to be loaded to display the same page, this is deemed mixed content.

Why Load Balancing Is Critical to Web Performance

Molly Wojcik | October 19, 2018 | Performance

The two most important demands on any online service provider are availability and resiliency. It takes a server a certain amount of time to respond to any given request, depending on its current capacity. If during this process, a single component fails or the server is overwhelmed by requests, both the user and the business will suffer. Load balancing aims to solve this issue by sharing workloads across multiple components rather than using a single server, thereby ensuring consistently fast website performance at any scale.

Vary User-Agent HTTP Response Header and its Effect in Varnish Cache

Shaun Guo | October 16, 2018 | Caching, Performance, Varnish Cache

The HTTP response header “Vary: User-Agent” plays an important role in how your website cache works. When set correctly in Varnish Cache, it will ensure that your visitors see the correct content, regardless of whether caching is applied or not.

Overcoming the Impact of Website Testing on Site Speed

Molly Wojcik | September 24, 2018 | Performance

Website testing tools can be very useful in helping improve user experience, allowing you to compare different iterations of a web page or application against each other, exploring a user’s experience of different variations of a particular page, or more extensive full stack testing in which backend elements are also tested for how they impact customer experience. However, an unfortunate side effect of using testing tools is that they can lead to slower site speeds. Many in the industry believe that a diminishment of page speed is an inevitable side effect to using website testing tools. You can overcome this, however, while still taking advantage of the benefits of website testing through using a different type of testing tool.
