check conformance of header order

Hello, am new to Splunk and this is my 1st post. I have logs that contain the request header information and need it to be in a particular order when the request is relayed to the server. How do I query and group logs by the order of header issued?

some example of headers expected "headers": {"host": "..", "accept-encoding": "..", "cache-control": "..", "referer": "..", "true-client-ip": "..", "user-agent": "..", "via": "..", "x-forwarded-for": "..", "x-forwarded-port": "443","x-forwarded-proto": "https", "connection": "keep-alive", "cookie": ".." }

Please describe your use case more. Who is relaying requests and to what server are they being relayed?

thanks @richgalloway, the use case is that we are expecting some edits to the header values by the CDN layer prior to issuing the request upstream (origin server). The edits get applied under some circumstances and when it does, the order of header changes. Wondering if there is a way to write a search query to groupby the order of headers received. Happy to clarify further.

Once you have the events parsed, you can process the fields in any order you choose. How you parse the events may have to change after the source changes how events are written. However, if you extract each field separately, without regard to it position in the event, then you be safe from future changes.
