I was wondering if anyone knew how the following is supposed to behave within a
transform when multiple transforms are chained:
//make sure we cache the UN-transformed data
TSHttpTxnUntransformedRespCache(txnp, 1);
TSHttpTxnTransformedRespCache(txnp, 0);
Suppose we have a transform X which invokes the above within it's
createTransfomration method and subsequently adds a header to the response to
indicate to downstream transforms that the contents are from untransformed
cache.
Now suppose we have a transform Y which optionally acts upon the output of
transform X depending on the presence or absence of certain query parameters as
defined by transform Y. When Y detects the header in the response it will add
itself to the chain on TS_EVENT_HTTP_CACHE_LOOKUP_COMPLETE.
What happens to the output of transform Y if no additional calls are made to?
//make sure we cache the UN-transformed data
TSHttpTxnUntransformedRespCache(txnp, 1);
TSHttpTxnTransformedRespCache(txnp, 0);
Will the output of Y be cached?
