This supports all the controllers that the new InkAPI supports, unclear if all or any of them are useful here. But the LOGGING controller definitely is.

        LOGGING          TS_HTTP_CNTL_LOGGING_MODE
        INTERCEPT_RETRY  TS_HTTP_CNTL_INTERCEPT_RETRY_MODE
        RESP_CACHEABLE   TS_HTTP_CNTL_RESPONSE_CACHEABLE
        REQ_CACHEABLE    TS_HTTP_CNTL_REQUEST_CACHEABLE
        SERVER_NO_STORE  TS_HTTP_CNTL_SERVER_NO_STORE
        TXN_DEBUG        TS_HTTP_CNTL_TXN_DEBUG
        SKIP_REMAP       TS_HTTP_CNTL_SKIP_REMAPPING

Example usage could be something like this, for a 10% log sampling rate:

cond %{REMAP_PSEUDO_HOOK}
cond %{RANDOM:100} >10
  set-http-cntl LOGGING FALSE

Here's a list of existing APIs that could be moved into this generic one:

tsapi void TSHttpTxnRespCacheableSet(TSHttpTxn txnp, int flag);
tsapi void TSHttpTxnReqCacheableSet(TSHttpTxn txnp, int flag);
tsapi TSReturnCode TSHttpTxnServerRespNoStoreSet(TSHttpTxn txnp, int flag);
tsapi void TSHttpTxnDebugSet(TSHttpTxn txnp, int on);
tsapi void TSHttpSsnDebugSet(TSHttpSsn ssnp, int on);
tsapi void TSSkipRemappingSet(TSHttpTxn txnp, int flag);

Would it be hard to added testing for this to pluginTest/header_rewrite/header_rewrite.test.py or add a new test?

Dunno, I think so? It'd have to setup logging, as well as verifying that the logging is happening or not happening? Just take my word for it, I mean, if I were wrong (in the code) don't you think I would know it?

It's all about trust, not testing. We must all swim naked together in volcanic hot springs in Iceland ASAP to build trust.

I rewrote / updated this to be more generic, now that we landed the new API as well.

Is this some sphinx voodoo or are you just winking at us twice?

Hmm seems pointless to initialize one of these and not the other.
