Introduction # HTTP response headers provide additional information about the server’s response to an HTTP request. These headers are essential for web developers and server administrators to ensure efficient and secure communication between clients and servers. In this blog post, we will discuss some of the most common HTTP response headers and provide example values for each header.
Introduction # The Internet has evolved in the last 2 decades a lot. HTTP/1.1 was not enough so we have HTTP2 now. The specification we used to transfer data between the client and the server has also evolved. From XML to JSON, now we have Protocol Buffer, which is a binary spec. Let’s dive deeper.
The picture below from Wikipedia shows how exponential data is growing.
Introduction # We have been using FastAPI along with the Test-Driven Development process to come up with an authentication system. Till now we can register to own tiny application using a username and password. We are also able to generate a JWT token to be classified as a logged-in user. But there is no point in logging in until the logged-in user can do something privileged. In this iteration of the series, we’d see how to access a protected endpoint using FastAPI and JWT. Given that we already have a JWT token.
Introduction # In the last couple of posts in TDD Auth with FastAPI we’ve been sustainably moved towards a web service that can let users register with the service. Now what?
We have already done the easy part. The next part is to look at the authorization. This involves letting the user log in. And only give access to what they are authorized for. Let us look at the login part first.
Recap # We have already seen how to enable HTTPS on a domain if you have a VPS and you are using Nginx. In one other post we have also talked about getting started with Ansible in which I wrote about basic concepts in Ansible such as inventory, module, playbook. We have also talked about Ansible Roles which are about directory structures.
Introduction # I have already posted about how we can automate installation of Jenkins & Nginx with Ansible. I have also done a post where I talk about how to enable HTTPS on a non-wildcard basis i.e. only for the root domain and not on subdomain.
Today I’ll go through how go get and configure a HTTPS certificate from Let’s Encrypt for all the subdomain. I’ll automate all these using Ansible.
Introduction # In 2014, Google hinted that they are running tests taking into account whether sites use secure, encrypted connections as a signal in our search ranking algorithms. This means it will affect SEO in some way. Today in the age of HTTP2, https is default. Default in the sense that many server software will only allow HTTP2 when https is configured.
Introduction # The internet is already growing, no need to say that. With that is growing demands, increasing load on existing infrastructure. New, better protocols are defined in every direction, let it be OpenAPI or HTTP/3. It is not limited to HTTP. With time there has been seen a significant boom in messaging protocols like RabbitMQ and similar related services like Amazon SQS. With this post I have tried to collect as much information as I can about
evolution of HTTP without getting too into any particular part.
Introduction # Are you lost between Handle, HandleFunc, and HandlerFunc? If the answer is yes then this post is for you. To understand these pretty well we need to be familiar with interafces. Although interface is just a keyword, it’s confusing at first when you are switching from Python like language; which does not have a similar keyword.
