Third-Party Handlers

Iris has its own middleware form of func(ctx iris.Context) but it's also compatible with all net/http middleware forms. See here.

Here's a small list of useful third-party handlers:

Middleware	Description
goth	OAuth, OAuth2 authentication. Example
permissions2	Cookies, users and permissions. Example
csp	Content Security Policy (CSP) support
delay	Add delays/latency to endpoints. Useful when testing effects of high latency
onthefly	Generate TinySVG, HTML and CSS on the fly
RestGate	Secure authentication for REST API endpoints
stats	Store information about your web application (response time, etc.)
VanGoH	Configurable AWS-Style HMAC authentication middleware
digits	Middleware that handles Twitter Digits authentication

Feel free to put up your own middleware in this list!
