Transaction ID

[Jeremy Payne]

Per end user request, does ATS generate a unique ID I can also use as
a transaction id?
I am thinking of creating an ID(hash) based on URL+some-random-string,
but want to make sure something isnt generated internally(and exposed
via some API), before starting this work.

The ID will then be added to something like a request header as the
request passes each cache tier. So now instead of having to
search/link child/parent log entries against multiple fields, I can
just use this ID(hash).Of course cache log filter will have to include
the request header containing the ID.

Thanks in advance!

Sort of. There is this -
https://docs.trafficserver.apache.org/en/latest/developer-guide/api/functions/TSUuidCreate.en.html#c.TSProcessUuidGet
That will get you a process unique ID. You can combine that with the
transaction ID to get a globally unique transaction ID. Look at
TSClientRequestUuidGet
as well.

My original email was based on a search through our internal 6.2.x
source.. which doesn't contain the uuid API calls.
Of course these calls are supported in 7.1.3..

Thanks for your assistance.
