Why use Query String Parser?

URLs encode arrays, booleans, and nested objects inconsistently. Paste a full URL or a raw query string to decode percent-encoding, split parameters, and spot duplicate keys that frameworks may silently overwrite.

Practical tips

  • Compare parsed output against server logs when debugging cache keys.
  • Watch for plus signs versus %20 in legacy systems.
  • Use REST Endpoint Tester when you need to replay the query against a live host.

Common questions

Does order of parameters matter?
Usually no for maps, but some caches include order in signatures—verify your stack.
Can this parse fragments (#)?
Fragments are client-side only and are not sent to servers; they are ignored for HTTP semantics.
