Thanks to the previous patch, it is now possible to add an action to dynamically change the maxumum number of connection retires for a stream. "set-retries" action may now be used to do so, from a "tcp-request content" or a "http-request" rule. This action accepts an expression or an integer between 0 and 100. The integer value is checked during the configuration parsing and leads to an error if it is not in the expected range. However, for the expression, the value is retrieve at runtime. So, invalid value are just ignored. Too high value is forbidden to avoid any trouble. 100 retries seems already be an amazingly hight value. In addition, the option is only available on backend or listen sections. Because the max retries is limited to 100 at most, it can be stored as a unsigned short. This save some space in the stream structure. |
