Instart Logic Debuts Next-Generation Software-Defined Application Delivery Platform for Modern Applications

  • Enables innovations for speed, security and scale.
  • Announces new performance features: JavaScript Interception and Browser Cache Purge.

PALO ALTO, Calif.--()--Instart Logic, the leading cloud application delivery provider that brings speed, security and scale to websites and applications, today announced at the O’Reilly Velocity Conference the next generation of its Software-Defined Application Delivery (SDAD) platform. The major update to the platform includes new performance features including JavaScript Interception that accelerates third party code, and development of Browser Cache Purge to extend cache control to the browser.

Today, cloud and mobile architectures are providing new ways to design and deliver web applications that enable faster time to market, personalized end-user experiences and improved business agility. Instart Logic’s SDAD platform is built from the ground up for these modern-day applications and gives customers increased programmatic access and control, delivering dramatically superior user experiences and performance boost over traditional content delivery networks (CDNs).

Next-Generation SDAD Platform

Instart Logic’s SDAD platform includes:

  • Expanded APIs and a new management portal for improved agility and end-to-end programmatic control.
  • A big data platform that enables consolidated real-time reporting and analytics of globally distributed information.
  • Embedded machine learning to automatically improve performance.
  • Nanovisor 2.0, an upgrade to its patented client technology, which enables new innovations in performance and security.

As part of its next-generation SDAD platform, Instart Logic today also announced two new performance features: JavaScript Interception and Browser Cache Purge.

JavaScript Interception

According to httparchive, the amount of JavaScript used by the top 100 websites has almost tripled in the last year, with 40 percent of these JavaScript requests being for third party content. Application publishers typically are not able to control the performance of third party content, which can negatively impact user experiences.

Instart Logic’s JavaScript Interception improves performance, availability and reliability by extending its recently announced JavaScript Streaming capability to intercept both static and dynamic third party content through its SDAD service.

This feature is made possible by the new Nanovisor 2.0 that includes an industry-first, client-side interception system, enabling runtime redirection of client-side asset requests. The JavaScript Interception solution:

  • Re-routes third party JavaScript requests through Instart Logic’s service, providing performance, availability and reliability.
  • Removes domain name lookup and connection establishment overhead.
  • Applies SmartSequence technology to third party JavaScript code.

JavaScript Interception is the first use case of this capability, but in the future will be deployed to redirect other third party elements such as CSS, fonts and images.

For more details on JavaScript Interception, read the Instart Logic technology blog.

Browser Cache Purge

Today, Instart Logic also announced it is developing a revolutionary new performance feature – Browser Cache Purge – that extends programmatic cache control to the browser. Browser Cache Purge changes the current model of web application development by making caching an integral component of application design. Current caching systems cannot manage browser cache and typically rely on a polling mechanism to manage cache currency, also known as “time to live (TTL).”

With Browser Cache Purge, publishers will be able to push changes to the browser via an API and clear browser cache instantaneously whenever necessary. This new capability improves performance by eliminating unnecessary network requests to check for current content and will fundamentally change how applications are designed. Instart Logic is initiating an Early Experience Program to recruit application publishers to provide input into how this capability impacts application design.

Programmatic Control with APIs

In addition, Instart Logic is opening up its SDAD platform and providing developers with deep programmatic control of the end-to-end delivery path with a complete set of APIs.

The new APIs include:

  • Account Management: programmatic control of account settings, user access and privileges.
  • Session Management: active management of authenticated sessions.
  • Configuration: full control of configuration settings for optimization features.
  • Statistics: user defined, near real-time reporting of all system activity.
  • Cache Management: real-time, end-to-end control of purging the cache.
  • Activity Reporting: complete management for searching, reading and updating tasks.

Pricing & Availability

Instart Logic’s JavaScript Interception solution is available today as part of the company’s SDAD platform. The APIs will be available this summer and included as part of the platform, with pricing starting at $5,000 a month.

Customers can sign up for the Browser Cache Early Experience Program starting today by visiting the Instart Logic Developer Central, which includes the Developer Community and API documentation.


“As Instart Logic’s first customer, we have worked closely with them to leverage their unique Software-Defined Application Delivery platform," said Ori Zaltzman, founder & CTO at Gogobot. “This has increased our site speed and applications performance to gain a competitive advantage. We enjoy watching Instart Logic develop new, innovative performance features such as JavaScript Interception, which helps solve the performance challenges with third party code, and are excited to see them opening up their SDAD platform with new APIs.”

“The future of application delivery will be based on software, not networks,” said Manav Mital, CEO of Instart Logic. “We’ve proven that our Software-Defined Application Delivery platform is the fastest solution on the market today.
