Question about port numbers in a url

[Solarion]

Good afternoon on this great weekend.

I have this which is giving headaches. I'm not overly familiar with url's and what not.

I do know that this works.



But this does not and it throws an "Invalid Port" error. Even the url changes color. Is there a reason for this?



If there is a way around this I would really appreciate your feedback.

Ports are unsigned 16 bit integers. 123456 overflows

haiboo i thought you an experienced programmer.Anyway iam not a programmer , but port numbers only go up to port 65535 , so thats why its throwing an invalid error.Make sure you select a port within the range of 1 to 65535.

* 0-65535 technically. Although port 0 is a wildcard

* 0-65535

Dont try get technical now.Put port number of 0 in , and lets see what happens ? App will most likely crash

Don't dumb it down now

I think deep down I didn't want to believe it was true, that ports can run out. I shall write a complaint to the internet and demand more ports.

cool i understand.Most programmers think that things like storage , memory , network capacity and cpu resources are infinite and will never run out.You have to explain to them , to try write code that is streamlined and optimized so their applications functions well

FYI, the 16-bit constraint comes from the TCP specification.

Why would you run out of ports? 65535 is a hell of a lot per machine.
