Slow browsing no joke for Joke

May 07, 2019

ApplianSys is pleased to announce that International Community School (ICS) in Singapore has chosen CACHEBOX to accelerate both HTTP and HTTPS content for its students.

As an American-curriculum international school, online content plays a key role in ICS’s teaching approach, so the school demands a high standard of user experience for its students.

Therefore, ICS maintains a relatively large 1Gbps connection to handle 350 Apple iPad and Chromebook devices. Yet it found that when ~200 students accessed the same lesson content simultaneously, network congestion quickly occurred, significantly slowing down browsing speeds.

Not wanting to pay out for a bandwidth upgrade just to cover short-lived demand, the school sought a more affordable solution in caching. By storing content and serving it locally, a cache offloads content from a school’s connection, eliminating congestion – and delivers it faster. But with half its network traffic delivered via HTTPS, ICS needed a cache to handle both HTTP and HTTPS traffic.

Network Manager Joke Jong found CACHEBOX was the perfect solution.

“The trend towards delivering web content via HTTPS has reduced the effectiveness of existing caches for many users around the world. But CACHEBOX fully supports HTTPS caching,” says ApplianSys Business Development Director Dave Gravell.

Once deployed, CACHEBOX’s impact was instant. Caching HTTPS – as well as HTTP – has resulted in significant additional bandwidth savings for ICS. Now the majority of prime learning content is served from local cache at LAN speed – often arriving many times faster than from the internet.

Joke is pleased with the results, “At ICS all types of learning content have been accelerated where it matters – in the classroom – significantly improving the overall student learning experience.”

Dave is keen for others to benefit, “If a school in Singapore, with plenty of fairly low-cost bandwidth, can see dramatic results with CACHEBOX, all international schools in the region will likely benefit –  even more so where bandwidth is scarce or more expensive.”


International Community School is an international school that teaches an American curriculum to a campus of 430+ students from more than 26 nationalities. Its international community service projects see it partner with ministries in Cambodia, China, India, Indonesia, the Philippines, and throughout southeast Asia.
