What does /*.php$ mean in robots.txt? -


i came across site uses following in robots.txt file:

user-agent: * disallow: /*.php$

so do? prevent web crawlers crawling following urls?

https://example.com/index.php https://example.com/index.php?page=events&action=upcoming

will block subdomains too?

https://subdomain.example.com/index.php

so do?

by spec means "urls starting /*.php$", isn't useful. there might engines out support custom syntax it. know support wild cards, looks regular expression syntax , i've not heard of supports in robots.txt.

will prevent web crawlers crawling following urls?

by spec: no.

if supports regexs, block first 1 not second one.

will block subdomains too?

no. each origin independent when comes robots.txt. subdomain site need own copy of resource.
