Hi,
I’d like to extend these two (existing) APIs
void TSRedirectUrlSet(TSHttpTxn txnp, const char* url, const int
url_len);
const char* TSRedirectUrlGet(TSHttpTxn txnp, int *url_len_ptr);
with this addition:
int TSRedirectRetriesGet()
This allows for a plugin using these API to do for example
1. Apply different changes to the redirection based on which attempt it
is (e.g. try a.example.com on the first try, and b.example.com on the second
try).
2. Allow it to stop retrying at will, before we hit the max number of
retries (e.g. avoid trying one host, a.example.com, repeatedly)
The naming of this API is a little less than ideal (I think these should have
been member of the Http / Txn family), but I picked a name that’s inline with
the existing APIs for consistency (stay within the “family”). I don’t think it
makes sense to have a Set() method on this, since this is an internal counter.
I’ve filed a Radar on this:
