Description
HTTP is the fundamental protocol of the World Wide Web. It enables the retrieval of information and data exchange between clients and servers over the internet. HTTP is simple, lightweight, and facilitates efficient communication.
✔Benefits
- Enables access to web content
- Supports various data formats
- Easy to use
✖Limitations
- Security risks during transmission
- Limits on data amount
- Possible delays
Trade-offs
Metrics
- Loading Time
The time required to load a webpage.
- Error Rate
The percentage of failed requests.
- Bandwidth Utilization
The proportion of bandwidth used compared to total bandwidth.
Examples & implementations
W3Schools
W3Schools uses HTTP to load content on its website.
Google API
The Google API uses HTTP for communication between clients and services.
Mozilla Developer Network
MDN uses HTTP to provide developer tools and documentation.
Implementation steps
1
Setting up the server
2
Configuring client settings
3
Testing the connection
⚠️ Technical debt & bottlenecks
Technical debt
- Unoptimized server configurations
- Outdated security certificates
- Redundant HTTP requests

Misuse examples
- Use in insecure networks
- Transmissions of sensitive data without encryption
- Lack of validation of user requests
Typical traps
- Expecting performance improvements without caching
- Ignoring security checks
- Neglecting updates
