HTTP 508 Loop Detected Error - Meaning & Fix

The HTTP 508 Loop Detected status code means the server stopped an operation due to an infinite loop. This issue occurred while processing a request involving extensive recursions or interactions. The operation as a whole was unsuccessful.

Main causes

Misconfigured server-side rewrite rules causing recursive redirection.
Poorly implemented WebDAV properties that create cyclic dependencies.
Errors in the client's request, particularly in the handling of "Depth: infinity", leading to unintended recursive operations.
Server-side scripts or configurations that inadvertently create infinite loops during data processing.

# Request example 
curl -X POST https://sandbox.oxylabs.io/ -H 'Accept: */*;q=0.8' -H 'Accept-Encoding: br' -H 'User-Agent: Mozilla/5.0'
