HTTP 1.1... Going back to basics. I actually thought I knew the basics. Turns out there are other allowed methods besides GET, PUT, POST, PATCH, DELETE, and OPTIONS like: - HEAD: same as GET with no response - CONNECT: establish a tunnel to the destination server - TRACE: request an application-level loop-back (loop-backs are often used to test the quality of a signal path for errors, or to debug physical connection issues), where the server responds almost the same message that it received Also, apparently, the minimum methods a general purpose HTTP server must support are GET and HEAD. If you found that interesting, I invite you to explore more of its documentation. This is the section where I got the above information: https://lnkd.in/gX9X2M4A

Does your HTTP POST endpoint return correct status code? From RFC9110 (HTTP Semantics): If one or more resources has been created on the origin server as a result of successfully processing a POST request, the origin server SHOULD send a 201 (Created) response containing a Location header field that provides an identifier for the primary resource created (Section 10.2.2) and a representation that describes the status of the request while referring to the new resource(s). https://lnkd.in/eFbDzYkr). #endpoint #rest #restapi

In http2, client and server has to establish TCP connection only once, which generally takes 50ms to 250ms(maybe more) depending upon how far the server is geographically located from the client. In http1, every request has to establish a new TCP connection. http2 can be a savior in polling since client doesn't need to establish new TCP connection periodically, quite interesting!

Could someone recommend resources for implementing an HTTP server from scratch in C? I've found the official HTTP RFC challenging to follow. I plan to explore MDN docs today.

Important update: Omniphlex v9.5.1 is now available! Release Notes: - Fixed problem that some triggers caused a memory-leak which would lead to insufficient resources on the server if the daemon was not restarted regularly - Fixed memory-leak in plugin “SimpleImageConvert” - Fixed problem with “Created By” value in workflow-description ...download from www.omniphlex.com

TCP uses a three-way handshake to establish a reliable connection. The connection is full duplex, and both sides synchronize (SYN) and acknowledge (ACK) each other. The exchange of these four flags is performed in three steps—SYN, SYN-ACK, and ACK—as shown in Figure 3.8. Step 1 (SYN): In the first step, the client wants to establish a connection with a server, so it sends a segment with SYN(Synchronize Sequence Number) which informs the server that the client is likely to start communication and with what sequence number it starts segments with Step 2 (SYN + ACK): Server responds to the client request with SYN-ACK signal bits set. Acknowledgement(ACK) signifies the response of the segment it received and SYN signifies with what sequence number it is likely to start the segments with Step 3 (ACK): In the final part client acknowledges the response of the server and they both establish a reliable connection with which they will start the actual data transfer

#𝟮.𝟯 𝗖𝘂𝗿𝗶𝗼𝘂𝘀 𝗖𝗼𝗱𝗶𝗻𝗴 - 𝗕𝘂𝗶𝗹𝗱 𝘆𝗼𝘂𝗿 𝗼𝘄𝗻 𝗥𝗲𝗱𝗶𝘀 𝗦𝗲𝗿𝘃𝗲𝗿 I have completed Part 2 which consists of implementing TTL, INCR and DECR commands usage on the server. 1. TTL enables to check the remaining time of expiry of a key. 2. INCR is able to increase the number value of a key by 1. If key is not present, it will add a key with value 1. 3. DECR is able to decrease the number value of a key by 1. If key is not present, it will add a key with value -1. Also the error handling structure has been refined as part of the update. Updated Source code can be found at- https://lnkd.in/gwA5dKhM Here is a demonstration of same.
