.NET implementation of URL shortening service
##How to set it up
All you need is to build and publish WebAPI to your IIS host server and configure database connection string in web.config file. On the first run database will be automatically created.
<configuration>
<connectionStrings>
<add name="ShortUrl" connectionString="Server=<SQL-SERVER-INSTANCE>;Database=ShortUrl;User Id=<USERNAME>;Password=<PASSWORD>;" providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>##How to use
The service cosists of two basic functionalities:
####Create short url Simple post of long URL to controller action "SHORT" will create record with short URL key and retrieve it back
POST /Short/ HTTP/1.1
Host: localhost:37626
Content-Type: application/json
Cache-Control: no-cache
"http://www.asp.net/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api"If the short URL already exists with the short URL key then existing short URL key is retrieved.
####Navigate to short url Passing the short URL key to service in GET request will return redirection header values (including long URL string) order to navigate browser to the long URL assigned to the key.
GET /1639fe HTTP/1.1
Host: localhost:37626
Content-Type: application/json
Cache-Control: no-cache##Settings

| CheckUrlAvailabilityTimeout | 5 | How many seconds to wait for a response when checking URL availability |
| KeyLength | 6 | Character length of short URL key for added URLs |
| CacheTimeout | 5 | How many minutes to keep key and URL after last request |
<configuration>
<appSettings>
<add key="CheckUrlAvailability" value="False"/>
<add key="CheckUrlAvailabilityTimeout" value="5"/>
<add key="KeyLength" value="6"/>
