Description: localdev
        ==========
        
        A command line tool that maps development domains (like *.myserver.dev) to a 
        set of servers running on localhost. This tool was built to dramatically reduce 
        [the pain](http://mikeferrier.com/2011/04/04/setting-up-wildcard-dns-on-localhost-domains-on-osx/) 
        of setting up multi-domain local development. It takes the place of a DNS 
        server like Bind or dnsmasq, and a reverse proxy like Apache or Nginx. 
        
        With localdev you can stop fussing with /etc/hosts and configuration files. 
        Instead, hook-up your development servers with a single command.
        
        ## Use
        
            sudo localdev --rules "niftythings.dev=5000, api.niftythings.dev=5001, *.niftythings.dev=5002"
        
        In the above example, three servers are running on localhost: a webserver on 
        port 5000, an api server on 5001 and a server hosting customer content on port 5002. 
        Localdev routes web requests to the three servers by matching the hostname of 
        each request to a rule, and proxying the request to the corresponding port.
        
        By default requests are routed to localhost. You can also route traffic to a 
        server running elsewhere, such as on your LAN:
        
            sudo localdev --rules "*.here.dev=5000, *.there.dev=192.168.1.10:5000"
        
        Sudo is required if you use the default ports 53 and 80 for handling DNS and 
        HTTP traffic. To run without sudo, you'd need to provide alternative ports, 
        which is pretty normal for HTTP, but setting up DNS on a port other than 53 is
        pretty weird. See the [reference](#ref) on option -D if this is important.
        
        ## Under the hood
        
        Localdev doesn't touch your system configuration. It's entirely contained 
        within a single process.
        
        When launched, localdev starts two services: a local DNS server that maps a TLD 
        (like .dev) to localhost, and a reverse proxy that routes HTTP requests to your 
        servers based on the configuration rules.
        
        Here's a little anecdote to clarify the process:
        
        > When you type "mysite.dev" into your browser, first your browser issues a 
        > DNS query to your primary DNS server. If installed correctly, localdev says 
        > "Yo, that server is on localhost". Then your browser is like, "word" and sends 
        > an HTTP request to localhost port 80. Then localdev slides over and says 
        > "Surprise! Me again.", and proxies the HTTP request to the destination server
        > according to the rules you defined. "Whatever," says your browser.
        
        The DNS is a lightweight server based on [devdns](https://github.com/colevscode/devdns). 
        The reverse proxy is based on [quickproxy](https://github.com/colevscode/quickproxy), 
        which is itself built on [Tornado](http://http://www.tornadoweb.org/).
        
        ## Installation
        
        For non python developers, using a mac or linux:
        
            sudo easy_install localdev
        
        For python people:
        
            pip install localdev
        
        ### Set localhost as your primary DNS server <a name="dnslist"></a>
        
        In order for localdev to work, your browser needs to use it for DNS resolution.
        This requires putting localhost (127.0.0.1) at the top of your system-wide DNS 
        server list. I recommend also adding Google's DNS addresses (8.8.8.8 and 
        8.8.4.4) as backup servers (since localdev isn't a general DNS server).
        
        To do this on a Mac, open System Preferences and open the Network pane. On the 
        left side, select the network adapter you use (most likely your wireless 
        adapter), and then click Advanced. Under the DNS tab, click the + button under 
        the DNS Servers list, and add 127.0.0.1, 8.8.8.8 and 8.8.4.4 in that order. 
        Click OK, then click Apply.

        ## Troubleshooting (Mac)
        
        If DNS was simple, this tool wouldn't be valuable. Unfortunately that also 
        means that it's difficult to make a DNS tool that works out of the box for 
        everyone. Here are some things you can check if localdev doesn't work on the  
        first try:
        
        - Use `dig` to see if localdev correctly resolves your domain name to 127.0.0.1
              
        
              dig mycoolsite.dev
        
        
          You should see something like:
        
              # dig mysite.dev
              ; <<>> DiG 9.8.3-P1 <<>> mysite.dev
              ;; global options: +cmd
              ;; Got answer:
              ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55138
              ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
        
              ;; QUESTION SECTION:
              ;mysite.dev.            IN  A
        
              ;; ANSWER SECTION:
              mysite.dev.     60  IN  A   127.0.0.1
        
              ;; Query time: 31 msec
              ;; SERVER: 127.0.0.1#53(127.0.0.1)
              ;; WHEN: Sun Feb  2 21:44:45 2014
              ;; MSG SIZE  rcvd: 44
          
          If there's no ANSWER SECTION, make sure you've correctly configured your 
          [dns server list](#dnslist).
        
        - Use `curl -v mysite.dev` to see if there's an error. Depending on the error, 
          you can try a few things:
        
          - `curl: (6) Could not resolve host: mysite.dev`
        
            In this case, try flushing the dns cache and restarting mDNSResponder:
        
                dnscacheutil -flushcache
                sudo killall -HUP mDNSResponder
        
            If that doesn't work, unload and reload mDNSResponder:
        
                sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
                sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
        
            More discussion [here](http://apple.stackexchange.com/questions/26616/dns-not-resolving-on-mac-os).
        
          - `curl: (52) Empty reply from server`
        
            See the discussion below about previous installations below.
        
        - If you previously installed Bind or dnsmasq, you may have to disable those 
          services. 
        
          Unload bind:
        
              sudo launchctl unload -w /System/Library/LaunchDaemons/org.isc.named.plist
        
          probably something similar for dnsmasq.
        
        - If you're forwarding port 80 to a non restricted port, like 8080, with ipfw 
          or pf, that could also be a problem. Try running localdev using that port:
        
              localdev -r mysite.dev=5000 -p 8080
        
          Generally, check your firewall settings to ensure that HTTP traffic can reach 
          localdev.
