.Net Core module install


  • .NET Core 2.1 or later.
  • Verify you have installed the Next-Gen WAF agent for your platform (e.g., Linux or Windows). Check out our Getting started with the agent guide.


  1. Download the latest Signal Sciences HTTP middleware using one these methods:

  2. Add the Signal Sciences HTTP middleware to your project. Replace <packagePath> with the path to SignalSciences.HttpMiddleware.<version>.nupkg and <sourcePath> with the folder-based package source to which the package will be added:

    nuget add <packagePath> -Source <sourcePath> -Expand
    dotnet add package SignalSciences.HttpMiddleware -s <sourcePath>
  3. Add the following sections to your application's appsettings.json file:

    2 "SigsciOptions": {
    3 "AgentEndPoint": ""
    4 }
  4. Configure the HTTP request pipeline with Configure:

    1Configure(IApplicationBuilder app, IHostingEnvironment env) {
    2 var sigsciOptions = Configuration.GetSection("SigsciOptions").Get<SigSciOptions>();
    3 app.UseSigSciHandler(sigsciOptions);
  5. Restart the web site service.


Ensure the AgentEndPoint value is set to the same IP and port configured with the Next-Gen WAF agent's rpc-address value. See the Windows agent installation documentation for additional information about Windows agent configuration options.

MaxPostSizeoptional, default: 100000A request body above this size will not be sent to the Agent.
AnomalySizeoptional, default: 524288If the HTTP response is this size or larger, log it with the Agent.
AnomalyDurationMillisoptional, default: 1000If the response took longer than this number of milliseconds, log it with the Agent.
ExpectedContentTypesoptional, no defaultAdds custom types that allow inspection to the conditional content-type list.
