Remove field from all documents in Elasticsearch index

October 29, 2019 by leonid_efremov Leave a Comment

For example, you need to delete field field.property from index_a:

POST index_a/_update_by_query?conflicts=proceed
{
  "script" : "ctx._source.field.remove('property')"
}

it’s removed field from all existed document

Now we have to done reindex operation:

POST _reindex
{
  "source": {
    "index": "index_a"
  },
  "dest": {
    "index": "index_b"
  }
}

now new index index_b documents have no field field.property.

ASP.NET site behind SSL offload proxy

April 26, 2019 by leonid_efremov Leave a Comment

If your application placed behind frontend proxy that apply SSL offload and you need to support SSL schema in response stream use this HttpModule:

public sealed class HttpOverrides : IHttpModule
{
    public void Init(HttpApplication app)
    {
        app.BeginRequest += OnBeginRequest;
    }

    private void OnBeginRequest(object sender, EventArgs e)
    {
        var app = (HttpApplication)sender;
        var request = app.Context.Request;
        var forwardedProto = request.Headers["X-Forwarded-Proto"];

        if (forwardedProto == "https")
        {
            request.ServerVariables["HTTPS"] = "on";
            request.ServerVariables["SERVER_PORT"] = "443";
            request.ServerVariables["SERVER_PORT_SECURE"] = "1";
        }
    }

    void IHttpModule.Dispose() { }
}

and then use this module in web.config:

<system.webServer>
    <modules>
        <add name="HttpOverrides" type="HttpOverrides" preCondition="integratedMode" />
    </modules>
</system.webServer>
