|

Disable the DNS resolution of the httpclient. Prevent the creation of the

"default" resolvers section.

Default value is off.

httpclient.resolvers.id <resolvers id>
|
||||
This option defines the resolvers section with which the httpclient will try
|
||||
to resolve.
|
||||
|
||||
Default option is the "default" resolvers ID. By default, if this option is
|
||||
not used, it will simply disable the resolving if the section is not found.

|
||||
However, when this option is explicitly enabled it will trigger a

httpclient.resolvers.prefer <ipv4|ipv6>
|
||||
This option allows to chose which family of IP you want when resolving,
|
||||
which is convenient when IPv6 is not available on your network. Default
|
||||
option is "ipv6".
|
||||
|
||||
httpclient.retries <number>
|
||||
This option allows to configure the number of retries attempt of the
|
||||
httpclient when a request failed. This does the same as the "retries" keyword
|
||||
in a backend.
|
||||
|
||||
Default value is 3.
|
||||
|
||||
httpclient.ssl.ca-file <cafile>
|
||||
This option defines the ca-file which should be used to verify the server
|
||||
certificate. It takes the same parameters as the "ca-file" option on the
|
||||
server line.
|
||||
|
||||
By default and when this option is not used, the value is
|
||||
"@system-ca" which tries to load the CA of the system. If it fails the SSL
|
||||
will be disabled for the httpclient.
|
||||
|
||||
However, when this option is explicitly enabled it will trigger a
|
||||
configuration error if it fails.
|
||||
|
||||
httpclient.ssl.verify [none|required]
|
||||
Works the same way as the verify option on server lines. If specified to 'none',
|
||||
servers certificates are not verified. Default option is "required".
|
||||
|
||||
By default and when this option is not used, the value is
|

"required". If it fails the SSL will be disabled for the httpclient.

Set the maximum time to wait for a connection attempt by default for the

httpclient.

Arguments :
|

<timeout> is the timeout value specified in milliseconds by default, but

3.11. HTTPClient tuning
|
||||
-----------------------
|
||||
|
||||
HTTPClient is an internal HTTP library, it can be used by various subsystems,
|
||||
for example in LUA scripts. HTTPClient is not used in the data path, in other
|
||||
words it has nothing with HTTP traffic passing through HAProxy.
