--- Comment #3 from corythearchit...@outlook.com --- Thomas, thank you for your rapid evaluation and response on this matter. The general use case is the servicing of a request in which the order of parameter evaluation is significant. http://host/resource?country=CA&postalcode=N7T5R4 Let's assume this is in context of a general infrastructure that evaluates each parameter in the order received (field validation being just one example of potential triggers). postalcode validation is dependent on the value of country. The specific scenario I am currently dealing with is porting a web service implementation from ASP/IIS to Java/Tomcat. The Microsoft IRequestDictionary.QueryString implementation respects order of insertion, while Tomcat scrambles the order as a result of the backing HashMap collection. I respect your position that there is no explicit specification of the server-side evaluation of HTML parameters. However, I also see no significance to the client-side specification of parameter order beyond the implication that the ordering is also significant to the processing server that consumes it. What other purpose could such an ordering possibly serve? Assuming equivalent performance, what portability issues could arise from a MORE determinate collection implementation? If anyone is currently relying on the iteration order of the existing HashMap implementation, a) they are in for a surprise anyhow, and b) the ServletRequest interface, unfortunately, provides no guarantees, relying on the generic Map and Enumeration interfaces, both of which defer to the implementation for behaviour in this regard. This decision could only be interpreted as an improvement in compliance (with the HTML specification). -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
