### Remarks

In development builds, [UnityWebRequest](/engine/6000.7/script-reference/unityengine/networking/unitywebrequest.md) is allowed to use plain text HTTP connections. Otherwise, it is only allowed to use HTTPS connections.

Choose this option if you want to use insecure plain text HTTP connections with local servers while developing your application, and secure HTTPS connections in a release build.

In the Editor, [UnityWebRequest](/engine/6000.7/script-reference/unityengine/networking/unitywebrequest.md) is always allowed to use plain text HTTP connections when you choose this option. To create a development build, enable **Development Build** in the **Build Profiles** window, or include [BuildOptions.Development](/engine/6000.7/script-reference/unityeditor/buildoptions/development.md) when you call [BuildPipeline.BuildPlayer](/engine/6000.7/script-reference/unityeditor/buildpipeline/buildplayer.md).
