How to ensure that a request is really proxied by CloudFlare?

对着背影说爱祢 提交于 2021-02-19 05:21:04
问题 In one of projects we use CloudFlare and its cf-connecting-ip header to get a visitor IP address. But I'm not sure that the info can be fully trusted. For example, a bad user somehow had obtained real IP of our server, and connecting directly to it, putting fake IP address to the cf-connecting-ip header, and pretending that it was a legitimate CF-proxied request. I examined headers for CF-proxied requests, and saw the cf-request-id header. But it's unique per a request, and I cannot see there

SignalR Core connections not being closed and bringing down IIS

≯℡__Kan透↙ 提交于 2021-02-11 17:51:11
问题 We have SignalR Core running in IIS and the connections are not being closed over time. This results in a 503 error: HTTP Error 503.2 - Service Unavailable The serverRuntime@appConcurrentRequestLimit setting is being exceeded. When recycling the apppool the Current Connections will drop to 0 and then back up to around 50 (as actual clients reconnect). Over the course of a day it can easily reach 2000. Not every connection is leaking - the number does decrease but trends upwards over time.

Certificate validation failed: validation of client side certificate fails when the certificate is validated

问题 I am trying to get mutual client certification to work in Azure. I am running a web app with this configuration: public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { services .AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme

Cloudflare and Chromedriver - cloudflare distinguishes between chromedriver and genuine chrome?

别来无恙 提交于 2021-02-10 04:28:08
问题 I would like to use chromedriver to scrape some stories from fanfiction.net. I try the following: from selenium import webdriver import time path = 'D:\chromedriver\chromedriver.exe' browser = webdriver.Chrome(path) url1 = 'https://www.fanfiction.net/s/8832472' url2 = 'https://www.fanfiction.net/s/5218118' browser.get(url1) time.sleep(5) browser.get(url2) The first link opens (sometimes I have to wait 5 seconds). When I want to load the second url, cloudflare intervens and wants me to solve

CloudFlare and socket.io

旧时模样 提交于 2021-02-07 02:50:30
问题 I'm using CloudFlare to implement a REST API. I need to add some notifications which are implemented with socket.io on Node.JS. When socket.io uses a live connection to keep client updated it will work because the connection is established between server-client, but what happens when socket.io does polling? Does CloudFlare use always the same server for each client? 回答1: WebSockets are standardised by the IETF in RFC 6455, this allows you to avoid polling behaviour and instead directly

Use Cloudflare Authenticated Origin Pull with GCP Cloud Run

帅比萌擦擦* 提交于 2021-02-05 11:22:08
问题 I'm wanting to put Cloudflare in front of my API hosted on Cloud Run. I'd like to ensure my Cloud Run app only accepts connections from Cloudflare (to avoid bypassing DDoS mitigation + rate limiting in Cloudflare). Is there any way to use Cloudflare's Authenticated Origin Pulls with Cloud Run? Other solutions that achieve the same effect are welcome too - however the key is I don't want traffic from non-Cloudflare sources to trigger a Cloud Run invocation (otherwise a DDoS could result in
