2 Replies and 851 Views (CLOSED) Incredibly bad performance with latest data file    851  2 Started by  Owen Marsh We use the API in memory mode, and recently updated to the latest data file in our dev environment. This environment does not see a huge amount of traffic (400 requests per second) and previously had an average latency of less than 5 milliseconds. Upon restarting the server with the new data file, average latency never went below 80 milliseconds, and often went over 1 second. The new data file was the only change. We updated to the latest version of the API (, but that ...

4 Replies and 782 Views [Closed] Default Property Values    782  4 Started by  TreSensaCoreDev When the default property is returned for a 'match.getValues(propertyName)' call, I would like to use null instead. The TrieProvider class contains a 'getDefaultPropertyValue(String propertyName)' method, which makes this easy to accomplish. (Simply check the returned value against the default.) Can something similar be done with the regular Provider or Match classes

1 Replies and 1155 Views (CLOSED) Useragents & dropwizard    1155  1 Started by  captmega I've reviewed the documentation available, checked the forum, and tried reading through the javadoc, but still can't quite figure out how to get started. I'd like to evaluate using this library / service in a dropwizard project (http://dropwizard.io) It uses embedded jetty and jackson to provide api endpoints, and I can easily get the user agent header string from a request. Could you provide some sample code for how I might initialize the WebProvider I tried using this as a guide, but i...

6 Replies and 5476 Views (CLOSED) Configuring the AutoUpdate service to use a proxy server    5476  6 Started by  JBraund Good afternoon, Following on from our previous question (https://51degrees.com/support/forum/g/posts/t/3949/-SOLVED--IP-Address-or-URL-to-whitelist-for-automatic-updates), our service provider has advised us that we would need to use a proxy to connect to the 51 Degrees end point. How can we configure the AutoUpdate service to use a proxy server when accessing the end point Thanks, James

3 Replies and 1179 Views (SOLVED) Java Webapp - Client Side Overrides not available    1179  3 Started by  JoelFGS I'm trying to get the client side overrides to work in my webapp so I can detect iOS device models. The core.js returned by FiftyOneDegreesServlet never contains the FODPO javascript, even when being requested from an iOS device. It's not entirely clear to me what needs to happen to get this to work since the documentation for the Java code is out of date. Here's what I'm doing: Map /51D/* to FiftyOneDegreesServlet. Installed the Listener and Filter. I have verified that the license file...
