Reverse Proxy Deployment FAQs

Question 1

How do I handle large file uploads through a reverse proxy?

Accepted Answer

You can use a Location block in your Apache config to set a higher LimitRequestBody value, allowing for larger payloads such as PDFs or images.

Question 2

Why are my API calls returning 404 errors behind the proxy?

Accepted Answer

This is typically caused by incorrect ProxyPass ordering or missing trailing slashes. More specific paths (like /api/) must be listed before general paths in your Apache configuration.

Question 3

How do I verify if a service is accessible from the proxy server?

Accepted Answer

SSH into the proxy server and use curl to test the internal IP and port of your service. If the connection is refused, the service may be bound only to localhost instead of 0.0.0.0.

Question 4

What is the importance of trailing slashes in ProxyPass?

Accepted Answer

Trailing slashes on both the source and target URLs are required for Apache to correctly strip the path prefix before forwarding the request to the backend service.

Question 5

Why should I use relative URLs instead of absolute ones?

Accepted Answer

Relative URLs ensure your frontend can communicate with the backend regardless of the external domain or sub-path used by the proxy, making the application highly portable.
