Imposter

Imposter looks for requests matching a base URL and then swaps them for a local file.

Installation

1. Install the ClickOnce app from here (or download, build and publish locally)

Configuration

1. Profile Name: Set it to whatever you would like. I usually set it to the project that I am working on.
2. Base URL: The URL that will be used as the base fragment to match your local files off of. It can be a full valid URL, or a fragment such as /js/. Just note that whatever comes after your Base URL will be used to match files. If your Base URL is /js/ and a URL is requested matching /js/min/test.min.js, we will look in the local directory for a folder named min with a file called test.min.js in it.
3. Local Directy: The directory that is searched for matching files to be served in place of remote files.
4. Port: The port the proxy is to run on.
5. Decrypt HTTPS Traffic: Will install a certificate created by Fiddler to decrypt traffic over HTTPS.
6. Overrides: A listing of specific hard coded fallbacks for when a requested resource is unable to be located. Very helpful for hot swapping minified for unminified files for debugging.
