[squid-dev] [PATCH] Use TCP_REFRESH_PENDING while waiting for IMS reply

[Eduard Bagdasaryan]

Hello,

This patch marks refresh-waiting transactions with TCP_REFRESH_PENDING.

Before this change, transactions initiating a refresh were still marked
as TCP_HIT*. If such a transaction was terminated (for any reason)
before receiving an IMS reply, it was logged with that misleading tag.
Now, such transactions are logged using TCP_REFRESH_PENDING[_ABORTED].

After the refresh (successful or otherwise), the tag changes to one of
the other TCP_REFRESH_* values, as before.

Regards,
Eduard.
