[[_sp-idp-httpclient]]

===== IDP HttpClient sub element

The `HttpClient` optional sub element defines the properties of HTTP client used
for automatic obtaining of certificates containing public keys for IDP signature
verification via SAML descriptor of the IDP when
<<_sp-idp-keys-automatic,enabled>>.

connectionPoolSize::
  This config option defines how many connections to the {project_name} server should be pooled.
  This is _OPTIONAL_.
  The default value is `10`.

disableTrustManager::
  If the {project_name} server requires HTTPS and this config option is set to `true` you do not have to specify a truststore.
  This setting should only be used during development and *never* in production as it will disable verification of SSL certificates.
  This is _OPTIONAL_.
  The default value is `false`.

allowAnyHostname::
  If the {project_name} server requires HTTPS and this config option is set to `true`
  the {project_name} server's certificate is validated via the truststore,
  but host name validation is not done.
  This setting should only be used during development and *never* in production
  as it will partly disable verification of SSL certificates.
  This setting may be useful in test environments. This is _OPTIONAL_.
  The default value is `false`.

truststore::
  The value is the file path to a truststore file.
  If you prefix the path with `classpath:`, then the truststore will be obtained from the deployment's classpath instead.
  Used for outgoing HTTPS communications to the {project_name} server.
  Client making HTTPS requests need a way to verify the host of the server they are talking to.
  This is what the truststore does.
  The keystore contains one or more trusted host certificates or certificate authorities.
  You can create this truststore by extracting the public certificate of the {project_name} server's SSL keystore.
  This is _REQUIRED_ unless `disableTrustManager` is `true`.

truststorePassword::
  Password for the truststore.
  This is _REQUIRED_ if `truststore` is set and the truststore requires a password.

clientKeystore::
  This is the file path to a keystore file.
  This keystore contains client certificate for two-way SSL when the adapter makes HTTPS requests to the {project_name} server.
  This is _OPTIONAL_.

clientKeystorePassword::
  Password for the client keystore and for the client's key.
  This is _REQUIRED_ if `clientKeystore` is set.

proxyUrl::
  URL to HTTP proxy to use for HTTP connections.
  This is _OPTIONAL_.

socketTimeout::
  Timeout for socket waiting for data after establishing the connection in milliseconds.
  Maximum time of inactivity between two data packets.
  A timeout value of zero is interpreted as an infinite timeout.
  A negative value is interpreted as undefined (system default if applicable).
  The default value is `-1`.
  This is _OPTIONAL_.

connectionTimeout::
  Timeout for establishing the connection with the remote host in milliseconds.
  A timeout value of zero is interpreted as an infinite timeout.
  A negative value is interpreted as undefined (system default if applicable).
  The default value is `-1`.
  This is _OPTIONAL_.

connectionTtl::
  Connection time-to-live for client in milliseconds.
  A value less than or equal to zero is interpreted as an infinite value.
  The default value is `-1`.
  This is _OPTIONAL_.
