Today, we’re excited to announce two related features that lower bandwidth costs and reduce origin load for Fastly customers, resulting in faster downloads for their users: Streaming Miss and Large File Support.

Fastly recently conducted an extensive analysis of which resources should be compressed. Today, the results of that analysis are reflected in the Fastly app, which allows our customers to adopt better gzip settings. This not only makes our customers' websites faster, but it will also reduce monthly bandwidth charges.

We recently decided to work with Leon Kessler at Catch Digital to introduce VCL that would make it easier for new Drupal customers to get up and running with Fastly. Here’s how we did it, and how you can use it to improve the performance of your websites, mobile applications, and APIs.

If you're caching URLs that include user input, such as a search box, and the search is case insensitive, there's a really easy way to increase your hit ratio: convert the URL to lowercase.

Based on our understanding of the POODLE vulnerability (mainly the fact that there is currently no workaround), and the fact that we have very little traffic running over SSLv3 (around .5% globally), we are disabling SSLv3 for all Fastly SSL customers, effective immediately. This will mainly affect users of Windows XP Pre-service pack 3 combined with IE version 6. If you are in this group, please upgrade to a more recent browser.

This blog post will outline (1) how you can log additional data in your Fastly logs, (2) how to update your logging format so that it’s both human-readable and easily analyzed by your logging providers, and (3) how you can analyze and spot trends in your data.

This week, we’re rolling out Inline Help, a new enhancement to our user interface that will make Fastly easier to use for new customers and seasoned experts.

Hooman Beheshti, VP of Technology at Fastly, recently gave a talk at Velocity NYC 2014 about the challenges CDNs face with dynamic content and how businesses can use programmatic means to fully integrate their applications with their CDN.

There's a Fastly module available called "boltsort" which allows you to easily sort the parameters in the query string, so that you will always end up with the same URL, no matter what order the consumer of your API placed them in.

Fastly is excited to announce that as of today, we support stale-while-revalidate and stale-if-error. As a company dedicated to building a better Internet, we work hard to identify and support new standards that move the Web forward. Read on for an explanation of how these Cache-Control extensions make the Web faster and more reliable for browsers and CDNs, and check out documentation of these features.

Today we’re excited to announce that Fastly has raised a $40 million Series C round.

Fastly customers can use ESI to cache pages that contain both cacheable and uncacheable content (such as user-specific information).

Vary is one of the most powerful HTTP response headers. However, if used incorrectly, it can cause problems for developers. Understand vary header best practices to reduce mistakes and improve performance.

Security is one of our top priorities at Fastly. We recognize that having your account compromised could have a profoundly negative impact on your business, leaving you and your customers vulnerable and at risk. So, with enthusiastic feedback from our customers, we've been testing out ways to improve account security features. Today, we're pleased to release two-factor authentication and IP account access restrictions.

Introduced in the most recent release (0.6.0), adaptive plots add a level of flexibility and interaction that was sorely missing in the library. In this post, we’ll talk about what this means, and how you can leverage the plots in your applications to create smooth, beautiful, and useful data visualizations.

In a blog post about caching with tracking cookies, I explained how Fastly’s edge scripting language allows businesses to cache things that were previously uncacheable as well as send data back via our real-time logging system.

But what happens when you need to cache something more complicated, such as a product that handles user interaction?

At Fastly, we believe that the freedom to experiment is what makes the web great. We're excited by the cutting edge breakthroughs in file encodings that are happening almost every day, making the web better and faster.

Next week, we’ll be traveling up to beautiful Portland, Oregon to attend OSCON, O’Reilly’s Open Source Convention. We’re extremely excited to sponsor, attend, and speak at the conference this year.
