What does an HTTP proxy do?
Most commonly, it lets you make your web browser look like it's on a different network.
For example, you can use the HTTP proxy to tell your browser that your computer is in a different country than it is, so you can access any site you want even if it's blocked in your home country. But an HTTP proxy doesn't only let you access blocked sites; it can also blocked sites, or any sites that you don't want your browser to try and access. Using an HTTP proxy to do that is known as anonymous browsing, and in this tutorial we'll be using a specific one called Privoxy.
In Part 1 of this tutorial series we had already looked at how to install Privoxy, and how to set it up for anonymous browsing. If you haven't done that yet, I suggest that you take a look at that first article before continuing to read this one. In Part 2 we'll look at the different ports that Privoxy uses, and in Part 3 we'll show you some more of the settings you can change to make Privoxy more useful.

What Ports Does Privoxy Use? As you can imagine, a popular way to use a program is to put it on a server somewhere and then connect to that server over the Internet. That way, anyone who wants to look at your program can do so without getting your IP address. To access a program through the web you need to know what ports the program uses. For example, if your web browser is on the port 80, you can always go to your web browser's website and look for it there. Your web browser will typically list the ports that it uses, including 80, and that information will give you the IP address of the website's server.
However, Privoxy doesn't actually communicate with a website; it communicates with itself. Because of this, we don't always need to use a website to check what ports a program uses.
What happens if I turn on proxy?
By default we are using a proxy to do our SSL traffic.
How do I view the certificate from a server? When you visit a URL on your browser, you're actually sending a request to a hostname that looks like a website. This site will respond with an HTTP response code of 200. If you open up the developer tools and look for certificate, you'll see the certificate details.
What is the difference between an SSL Certificate and the SSL certificate? SSL certificate is an encrypted string that describes the owner of a website. A certificate is bound to a private key which is used for encrypting and decrypting the messages that are sent through a network. An SSL certificate will work both on a website and a website that uses HTTPS.

Should I use proxy or not?
Hi I have read on a forum recently that proxy servers should be avoided.
In essence, the reason being is that proxy servers are expensive, and that when you pay for your proxy server from your ISP to pass along requests to a different location, the requests still appear to come from your local IP address, thus slowing down your connection. If the request is slow, or the data stream not as fast, the other end (the website) has the time to notice and may rate you as slow. Also, proxies will add a layer of complexity, more overhead, and so on.
If the above statement is true, that means that using a proxy server will be very slow, right? Then the question is. If the proxy I'm using to bypass censorship comes from a server within my local network. Am I not using a proxy at all, but just a local router with a WAN/LAN port and forwarding incoming requests?
I appreciate anyone can shed some light in my question. Yes it's going to be pretty slow. They can only cache the page they requested, as they don't know what the full url path or full headers would be. Using such a cache would limit your ability to browse the internet. They're probably not caching them because it takes up more space to cache a whole website than a single http request.
If the proxy is on a private WAN port, then the traffic is still going to be going through the public internet, but will be much faster because it doesn't have to traverse all the hops like the main internet would. The latency might not seem that bad depending on how much data you're pushing through the network, and if the site you're going to is a well-trafficked one, they should be able to handle this type of load without causing it to slow down.
Should the HTTP proxy be turned on?
Is the proxy settings are
Appropriate?
Can we turn off HTTP 1.1 features we don't need (eg TLS, IPv6)? - If I enable TLS, do all my client users automatically see TLS encrypted requests when connecting to your app? Does setting TLS to required or on require setting a "client required" checkbox? Will enabling SSL/TLS give me "red" HTTP statuses? - Do I need TLS encryption when all traffic between the server and its clients is https? - Do I need http/2? - Do I need to enable the client certificate requirement? - Do I need to specify the ssl client certificate file path with a .pem extension? - Do I need a certificate for each user? - Are they optional? Does it work if I provide my own certificate? Do HTTPS Requests Have A Timeout? HTTPS connections can typically take multiple seconds depending on. Many factors. Therefore, the client may wait for the time to elapse before it retries in the face of a "connection refused" error. When using HTTP2, is it necessary to configure a time to wait for. A connection to the origin server in order to make a. Retransmission? What are the limits of re-authentication (redirects)? Does it really. "cache" the previous credentials? Do I need to configure these redirects? If I have many different users, how many can be authenticated through this "same server" authentication? Does this service provide the capability to create temporary passwords? Can I configure an application-specific token as the basis of one-time. Reuse of the user account identity? Is it possible to cache the response of an http/2 connection, like a "session"? Are cookies part of http/2? If so, do they get set once per request in http/2, like GET requests? Can HTTP/1.x connections be "reused", eg for the same app? Can HTTP/2 connections be reused in this manner, or are they not. Intended for that?
