The general docs for that are here:

https://wiki.shibboleth.net/confluence/display/IDP30/FileBackedHTTPMetadataProvider


In particular see these FAQs and sections:

In the absence of any validUntil and cacheDuration on the metadata 
document's root element itself, the actual default refresh cycle is 
based on the default config values and should be 3 hours:

maxRefreshDelay * refreshDelayFactor = PT4H (default) * 0.75 (default) 
= 3 hrs
