hi, IIS+Lucee, IIS returns 400 error after 30secs or so for one of long requests - I have suspision that IIS don't want to wait long enough. Anyone knows how to politely ask IIS not to hurry

couple ways to do it here: https://stackoverflow.com/questions/2414441/how-to-increase-request-timeout-in-iis

Thanks, tried that. Appeared something happens interesting than timeout 🙂 HTTP request is not seem to get to Lucee, it's not in its logs, but in IIS logs it's present...

what's the request method (verb)

is it intermittent - like some calls to x.cfm get through fine to tomcat and others don't make it out of IIS? Or this one page or directory of CFMs can't be called? did you check you don't have some old URL rewrite rules in IIS that are intercepting it. or request filtering setup in IIS? That can give rise to these type of issues e.g. https://stackoverflow.com/questions/67578286/iis-page-url-rewrite-gives-a-http-error-400-with-parameter-string-longer-than-26
