Compiled 'proxy/http/remap/NextHopHealthStatus.cc' against our internal 9.1.2 branch. Failure theshold is incrmeneted as expected with 'down' server being marked as unavailable. In the below access log sample, note the 3s ttms while the down server is being tried and timedout. After try 9, next_hop marks the server as 'unavailable' and immediately sends the request to the available server. Threshold is set to 10. #cqts|cqtn|chi|chp|phi|caun|cqhl|cqcl|pssc|crc|ttms|cfsc|pshl|pscl|psql|cqhm|cqus|cquuh|cquup|psct|phr|nhi|shn|"Age"|"UserAgent"|X-Forwarded-For|Cache-Control|pqhl|pqcl|pfsc|sshl|sscl|sssc|cqpv|Referer|c-Range|s-Range>|stms|xx|ts_ms_ua_begin|xxx|ats_int 1651526642|02/May/2022:21:24:02 -0000|172.16.21.222|32608|0.0.0.0|-|92|0|200|TCP_MISS|3933|FIN|235|0|235|HEAD|http|edge.com|/?16786|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"4"|"try-2"|-|-|229|0|FIN|238|0|200|http/1.1|-|-|-|3|-|1651526642266|1|- 1651526646|02/May/2022:21:24:06 -0000|172.16.21.222|32612|0.0.0.0|-|91|0|200|TCP_MISS|3023|FIN|235|0|235|HEAD|http|edge.com|/?8174|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"3"|"try-3"|-|-|228|0|FIN|238|0|200|http/1.1|-|-|-|2|-|1651526646218|1|- 1651526649|02/May/2022:21:24:09 -0000|172.16.21.222|32616|0.0.0.0|-|91|0|200|TCP_MISS|3534|FIN|235|0|235|HEAD|http|edge.com|/?5077|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"3"|"try-4"|-|-|228|0|FIN|238|0|200|http/1.1|-|-|-|1|-|1651526649260|1|- 1651526652|02/May/2022:21:24:12 -0000|172.16.21.222|32620|0.0.0.0|-|92|0|200|TCP_MISS|3470|FIN|235|0|235|HEAD|http|edge.com|/?24473|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"4"|"try-5"|-|-|229|0|FIN|238|0|200|http/1.1|-|-|-|4|-|1651526652809|2|- 1651526656|02/May/2022:21:24:16 -0000|172.16.21.222|32624|0.0.0.0|-|92|0|200|TCP_MISS|3542|FIN|235|0|235|HEAD|http|edge.com|/?31668|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"3"|"try-6"|-|-|229|0|FIN|238|0|200|http/1.1|-|-|-|2|-|1651526656297|1|- 1651526659|02/May/2022:21:24:19 -0000|172.16.21.222|32628|0.0.0.0|-|92|0|200|TCP_MISS|3725|FIN|235|0|235|HEAD|http|edge.com|/?10137|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"4"|"try-7"|-|-|229|0|FIN|238|0|200|http/1.1|-|-|-|2|-|1651526659858|0|- 1651526663|02/May/2022:21:24:23 -0000|172.16.21.222|32632|0.0.0.0|-|92|0|200|TCP_MISS|3121|FIN|235|0|235|HEAD|http|edge.com|/?31030|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"3"|"try-8"|-|-|229|0|FIN|238|0|200|http/1.1|-|-|-|2|-|1651526663601|1|- 1651526666|02/May/2022:21:24:26 -0000|172.16.21.222|32636|0.0.0.0|-|91|0|200|TCP_MISS|3248|FIN|235|0|235|HEAD|http|edge.com|/?4608|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"3"|"try-9"|-|-|228|0|FIN|238|0|200|http/1.1|-|-|-|1|-|1651526666742|1|- 1651526670|02/May/2022:21:24:30 -0000|172.16.21.222|32640|0.0.0.0|-|93|0|200|TCP_MISS|6|FIN|235|0|235|HEAD|http|edge.com|/?24660|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"0"|"try-10"|-|-|230|0|FIN|238|0|200|http/1.1|-|-|-|1|-|1651526670007|0|- 1651526670|02/May/2022:21:24:30 -0000|172.16.21.222|32642|0.0.0.0|-|93|0|200|TCP_MISS|6|FIN|235|0|235|HEAD|http|edge.com|/?22349|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"0"|"try-11"|-|-|230|0|FIN|238|0|200|http/1.1|-|-|-|2|-|1651526670027|1|- 1651526670|02/May/2022:21:24:30 -0000|172.16.21.222|32644|0.0.0.0|-|93|0|200|TCP_MISS|2|FIN|235|0|235|HEAD|http|edge.com|/?10863|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"0"|"try-12"|-|-|230|0|FIN|238|0|200|http/1.1|-|-|-|1|-|1651526670049|1|- 1651526670|02/May/2022:21:24:30 -0000|172.16.21.222|32646|0.0.0.0|-|92|0|200|TCP_MISS|7|FIN|235|0|235|HEAD|http|edge.com|/?4679|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"0"|"try-13"|-|-|229|0|FIN|238|0|200|http/1.1|-|-|-|0|-|1651526670067|0|- 1651526670|02/May/2022:21:24:30 -0000|172.16.21.222|32648|0.0.0.0|-|93|0|200|TCP_MISS|3|FIN|235|0|235|HEAD|http|edge.com|/?16688|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"0"|"try-14"|-|-|230|0|FIN|238|0|200|http/1.1|-|-|-|1|-|1651526670087|0|- 1651526670|02/May/2022:21:24:30 -0000|172.16.21.222|32650|0.0.0.0|-|93|0|200|TCP_MISS|6|FIN|235|0|235|HEAD|http|edge.com|/?26145|text/html|PARENT_HIT|172.16.21.223|origin-backup.com|"0"|"try-15"|-|-|230|0|FIN|238|0|200|http/1.1|-|-|-|2|-|1651526670105|1|- -- This is an automated message from the Apache Git Service.
