HttpRequestException handling

[michaelfoster9]

Hello, I have been using this library and I love it. I have implemented some error handlers using your OnFailure methods. That works great for failure responses returned from the server. What is the strategy for handling HttpRequestExceptions which would get thrown, for example, if the users internet connection was down.

It would be nice to be able to hande that within this framework. Please let me know if there is a way to do that, or if that is a possible future feature.

Yep, this can be done.

• I've added Action<HttpRequestException> HttpRequestExceptionHandler to the HttpRequestBuilder class.

• I updated the send method to catch the exception and, if an action has been defined, it will pass that exception to the action and then return null. If that action hasn't been defined, it will rethrow the exception. You can always rethrow the exception in the handler if you want to.

• I added the extension method OnHttpRequestException that will allow the action to be defined using the same fluent syntax that is the core of this library.

All this will be in the v3.0 release.

This has been deprecated in version 4 in favor of using a more comprehensive tool such as Polly.
