Great video! Though I find one thing confusing in your video - you mentioned that we need to configure a separate proxy for each application. it is correct that proxies operate at application level but it means that it can operate at the application layer (Layer 7 of the OSI model) and are aware of the specifics of different protocols like HTTP, HTTPS, and FTP.
The modern proxies can handle different types of proxies, for eg. Squid proxy can manage both HTTP and HTTPS traffic.

Worth spending time, good explanation for beginner 👍

I have one another doubt is as u said proxy server works at application layer and we need to setup different proxy for each application means i don't understand this . You mean to say if I have 3 different web application than i need 3 different proxy servers isn't? If is this the case than why ? Why need 3 different proxy servers to service multiple applications because you also explained multiple clients can request to proxy servers and they could be different applications/we applications right?

[Anjali_Ranveer_Singh]

please explain Proxy v/s API Gateway as well

9:00 how is grouping useful? Suppose I send some abc request on Google. You sent xyz request. How does it send as single request? Or if it goes sequentially won't opposite server has rate limiting? Or some queue will be used by proxy?

Hello Shreyansh, amazing explanation!
How do we send data from VPN server to destination server as at VPN server we have decrypted the data so again it is open to vulnerabilities, right?

[gurupreetsingh]

Good explanation but in case of forward proxy as you explain no server can talk or know the client because proxy server send the request to actual server by its IP but here is the catch if actual server want to know the IP of client it can be known by using http headers of request named X-Forward-For, right than how client can hide from actual server... Don't understand it 😢

[mayursamnani]

What is meant by group of requests here?

[ankitgupta-phnk]

Can we use proxy and reverse proxy both at a same time ?

[jaiswalharshit]

I am still confused in Reverse Proxy. Can you help Shrayansh?

[iamgauravnigam]

Hi! I have a small doubt, if CDN sits between client and server, shouldn't it be considered as a forward proxy rather than a reverse proxy?

[biswajitnaik]

If I relate DNS with forward proxy then it is fine.🤔

[bhatnagarcapital]

I love your mom and child example Shrayansh

[ANSHULGUPTA]

how to hide ips of server from the client? What if client knows ip and directly wants to access the server? how to handle that?

[rishabh]

Really need to be focused on the points when explaining the difference.
