Editing Miscellaneous Config Options (section)

== R ==

* '''recaptcha''' - Configuration for [[Recaptcha field]]s.
** '''ignore_countries''' - Array reference of ISO-639-1 two character codes for countries who should be automatically rejected. (Without a setting no countries are automatically rejected).
** '''private_key''' - The secret key generated by registering the hostname of the EPrints repository as a reCATPCHAv2 site.
** '''public_key''' - The site key generated by registering the hostname of the EPrints repository as a reCATPCHAv2 site.
** '''timeout''' - The maximum time to wait for a response from ReCAPTCHA.  (Without a setting LWP's default of 180 seconds is used. ReCAPTCHA is usually fairly quick to respond, so there is not really any need to set this).
* '''recaptcha3''' - Configuration for [[Recaptcha3 field]]s.
** '''ignore_countries''' - Array reference of ISO-639-1 two character codes for countries who should be automatically rejected. (Without a setting no countries are automatically rejected).
** '''min_score''' - The minimum score reCAPTCHAv3 needs gives for the request for it to be valid.  (Without a setting Google's default of <code>0.5</code> is used).
** '''private_key''' - The secret key generated by registering the hostname of the EPrints repository as a reCATPCHAv3 site.
** '''public_key''' - The site key generated by registering the hostname of the EPrints repository as a reCATPCHAv3 site.
** '''timeout''' - The maximum time to wait for a response from ReCAPTCHA.  (Without a setting LWP's default of 180 seconds is used. ReCAPTCHA is usually fairly quick to respond, so there is not really any need to set this).
* '''request_copy_cc''' - Array reference of email addresses that should be cc-ed in on all requests submissions that lead to an email being sent.
* '''<font style="color: red;">required_formats</font>''' -  Allows the definition of either an array reference or a function that will generate an array reference of required formats for documents. <font style="color: red;">This is a legacy option. <code>EP_TRIGGER_VALIDATE_FIELD</code> [[Triggers|trigger function]] should now be used instead.</font>
* '''retain_embargo_dates''' - Whether embargo dates for documents should be retained when the embargo date has been reached.  This may be useful if EPrints integrates with a third-party application that needs to retain embargo dates.  (Without this setting <code>bin/lift_embargos</code> will remove dates once the embargoes expire.  Otherwise, validation warnings for both the dates being in the past and documents still having embargo dates when they are public will be generated).
* '''rewrite_exceptions''' - Array reference of paths that should not be served by EPrints's Perl handler and should be served directly by Apache or some other handler.
* '''robotstxt'''
** '''crawl_delay''' - Adds crawl delay configuration to robots.txt.
*** '''default_seconds''' - The default number of seconds all other user agents (bots) should wait between crawl requests.  (without a setting no default crawl delay will be set).
*** '''seconds''' - The number of seconds for specified (i.e. more aggressive) user agents (bots) should wait between crawl requests.  (Without a setting <code>10</code> seconds will be used).
*** '''user_agents''' - Array reference of specific (more aggressive) user agents that require a (greater) crawl delay.  (Without a setting no user agents will have a crawl delay, unless <code>default_seconds</code> is set).
