transform plugin - disable cache option
Http transaction state machine contains cache lookup step.
Can I disable it?
If not, do I need to add Hook for TS_HTTP_POST_REMAP_HOOK which will call to perform a cache_lookup stage and return miss?
In this case the next step is TS_HTTP_CACHE_LOOKUP_COMPLETE_HOOK which has 4 options (miss, no-match, stale and fresh), Do I have to implement this option (always return - miss), or its default is miss.
Another part of my implementation do perform caching.

I understand that Performing TSHttpTxnConfigIntSet will affect only current transaction.
As for the second option, part of my implementation does caching. Is setting proxy.config.http.cache.http configuration value in records.config will not affect it.
Thanks YosefK.

yup
TSHttpTxnConfigIntSet(txnp, TS_CONFIG_HTTP_CACHE_HTTP, 0), which is the same as setting proxy.config.http.cache.http.
