Encountering a 500 Internal Server Error can be a web developer’s nightmare, especially when it pops up during GET or POST requests. It’s like hitting a roadblock with a sign that reads “Something went wrong, but I won’t tell you what.” Frustrating, right? Let’s dive into why these errors occur and how to tackle them, keeping things straightforward for everyone from curious customers to seasoned developers.
The Mystery of the 500 Internal Server Error
Our journey begins with a peculiar case: customers running load tests on their applications started reporting intermittent 500 Internal Server Errors. Oddly enough, these errors didn’t show up when making GET or POST requests directly from a browser. So, what gives?

A Closer Look at the Culprit
After some detective work, we pinpointed the issue. Many web applications, it turns out, don’t play well with missing request headers. While browsers automatically append essential headers to every request, the same can’t be said for all client requests, especially those simulated during load testing. Here are some of the headers that could be missing, leading to those dreaded 500 errors:
- Accept:
application/json;charset=utf-8,*/* - Accept-Encoding:
gzip, deflate, sdch, br - Accept-Language:
en-US,en;q=0.8,ro;q=0.6 - Cache-Control:
no-cache - Connection:
keep-alive - Host:
your_host:8080 - Pragma:
no-cache - Referer:
https://your_host:8080/ui/index - User-Agent:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.106 Safari/537.36
The absence of these headers in client requests can leave web applications befuddled, resulting in 500 Internal Server Errors.
