The holidays are upon us, and we thought you'd like a gift from us to you. Ishlangu 3.2 has been released today. We advise all our customers to update to this release as it contains fixes in key areas of the system.

TCP Fast Open

TCP Fast Open has been generally available for some time now, but only recently have products such as Apple's iOS and Google's Chrome software started to implement it. We thought it was about time to add it to Ishlangu. From this release all you need to do is enable TCP Fast Open on your proxies and start enjoying its benefits.

Google's TCP Fast Open Research Article may interest you as well. In summary, it states that: "Based on traffic analysis and network emulation, we show that TCP Fast Open would decrease HTTP transaction network latency by 15% and whole-page load time over 10% on average, and in some cases up to 40%."

Bug Fixes / Enhancements

Ishlangu 3.2 has fixes for a few important features within the application. We recommend that all our customers upgrade to resolve these issues.

SSL Proxy fails to start

When loading some certificates for proxy use, Ishlangu invalidated the certificate by corrupting the certificate's format. This resulted in the proxy failing to start up as it could not use the certificate in question. Ishlangu now loads the certificate and starts the proxy as expected.

HTTP/2 Client Cookies

When clients sent multiple HTTP/2 cookies to the proxy, Ishlangu would only send one of the cookies to the backend server. Ishlangu now prcoesses the HTTP/2 cookies and sends them to the backend server.

Responses from backend servers hang

If your proxy was configured with a uControl Response Rule, there was a chance that the response from the backend server would hang and that the client would never receive the response. This issue has now been resolved,.
