Before the regular IIS process, the module makes a call to the DataDome API using a keepalive connection.
Depending on the API response, the module will either block the query or let IIS continue the regular process.
The module has been developed to protect user experience as if any error was to occur during the process or if the timeout was reached, the module would automatically disable its blocking process and allow those hits.
This module is compatible with .NET Framework 3.5 or later and can be executed using any web server with support of ASP.NET HTTP Modules (e.g. IIS 6+, IIS Express, XSP, Apache with mod_mono).
DataDome integration was successfully tested on Azure VM and Azure WebApp.

Registering with Owin
AspNet Dome supplied with the method extension to register the middleware. Below there is an example of the Startup entry point configuration.
using System;
using Microsoft.Owin;
using Owin;
using DataDome.Owin;
[assembly:OwinStartup(typeof(Demo.Startup))]
namespace Demo
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.UseDataDome();
// All middleware after Data Dome will be shielded.
}
}
}update your existing Web.config and add section above with module registration.
<configuration>
[...]
<system.webServer>
[...]
<modules>
[...]
<add name="DataDome" type="DataDome.Web.ConnectorHttpModule, DataDome.SystemWeb" />
</modules>
</system.webServer>

Module can be configured using appSettings section of the Web.config file. Like in the following example:
<configuration>
[...]
<appSettings>
[...]
<add key="dome:domain" value="api.datadome.co" />
<add key="dome:protocol" value="http" />
<add key="dome:license" value="...you secret license key..." />
</appSettings>
</configuration>dome:domain
