  • Adjust resource limits such as connection pools and memory usage to handle peak loads without failure.
  • Configure Retry Logic:
  • Implement retry logic for transient errors to improve the resilience of the application.

Example Configuration Snippet

Below is a sample configuration snippet for a proxy server (e.g., Nginx) to handle proxy requests effectively:

“`nginx
http {
server {
listen 80;
location / {
proxy_pass http://upstream_server;
proxy_connect_timeout 10s;
proxy_read_timeout 30s;
proxy_send_timeout 30s;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
}
“`

This configuration sets timeout values and ensures that necessary headers are forwarded, which can help in reducing proxy errors.

I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
