http-reverse-proxy
==================
Provides a simple means of reverse-proxying HTTP requests. The raw approach
uses the same technique as leveraged by keter, whereas the WAI approach
performs full request/response parsing via WAI and http-conduit.
## Raw example
The following sets up raw reverse proxying from local port 3000 to
www.example.com, port 80.
```haskell
{-# LANGUAGE OverloadedStrings #-}
import Network.HTTP.ReverseProxy
import Data.Conduit.Network
main :: IO ()
main = runTCPServer (serverSettings 3000 "*") $ \appData ->
rawProxyTo
(\_headers -> return $ Right $ ProxyDest "www.example.com" 80)
appData
```
## HTTPS example to proxy bing.com
The following example sets up reverse proxying froming to www.bing.com
from localhost port 3000:
``` haskell
import Network.HTTP.Client.TLS
import Network.HTTP.ReverseProxy
import Network.Wai
import Network.Wai.Handler.Warp (run)
main :: IO ()
main = bingExample >>= run 3000
bingExample :: IO Application
bingExample = do
manager <- newTlsManager
pure $
waiProxyToSettings
( \request ->
return $
WPRModifiedRequestSecure
( request
{ requestHeaders = [("Host", "www.bing.com")]
}
)
(ProxyDest "www.bing.com" 443)
)
defaultWaiProxySettings {wpsLogRequest = print}
manager
```
After running it, you can visit [http://localhost:3000](http://localhost:3000) to visit
the search engine's page.
