gwt - What may be an efficient way to judge whether a user stays on the same domain while browsing (using a Firefox extension)? -


while browsing website, www.example.com, possible user enters subdomain www.sub.example.com

but base webdomain remains same.

in firefox extension, need develop "session" remains active until user remains on same domain.

a simple solution extract domain url first. split string "." token. thus, sub , example second case , example second case. can compare both. if equal, deduce domains same.

though might work, seems more hack , might prone false positives/negatives.

is there more efficient / cleaner solution same problem?

info: using gwt build extension

you should use nsieffectivetldservice, handle things sub.example.co.uk correctly. can pass nsiuri instance nsieffectivetldservice.getbasedomain(), aadditionalparts parameter should zero. http://sub.example.co.uk/foo example.co.uk - actual "domain" part. can compare domain names 2 urls.
