Question on robots.txt

[oschihin]

Websites / departments in my organisation usually have a robots.txt with the following simple entry:

User-agent: *
Disallow: /*?*
Sitemap: https://www.[domain].org/sitemaps/[domain].xml

I am not sure of how to deal with it, using heritrix 3.4 to crawl. I tend to set <property name="robotsPolicyName" value="ignore"/>, but wonder if this is a) considered friendly and b) has negative sideffects. So the question is:

• How does heritrix deal with the Disallow statement above? In my interpretation, it excludes just all URLs with a ? anywhere. But could heritrix treat this more "greedy", i.e. disallow everything?
• Does heritrix consider the Sitemap statement?

Heritrix does not currently support sitemaps (although there's a draft pull request adding it: #262) and does not support wildcards in Disallow lines (feature request #250). I haven't tested it but I would guess the rule Disallow: /*?* will be interpreted as matching paths that actually start with the literal string /*?. It will not match /index.html?foo.
