Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I entered a URL with a very long parameter on Stack Exchange.

I have type this url

It shows a blank screen , does not shown any messages.

enter image description here

We need to show a “Page Not Found” message, same as what you did on other Stack Exchange pages.

This question came from our discussion, support, and feature requests site for professional and enthusiast programmers.

Did you find a real link somewhere that has this issue? – Stijn Apr 17 '14 at 11:06
@Stijn , Sorry, I can't get you. What you mean? – Ramesh Rajendran Apr 17 '14 at 11:07
What I'm asking is, did you try this purely to see if it would break, or is there a page somewhere that has a really long link that is broken by this bug? – Stijn Apr 17 '14 at 11:08
I got tis problem, When i add extra parameter values (like query string) in the URL – Ramesh Rajendran Apr 17 '14 at 11:10
@TheGuywithTheHat , It's very cheating, Where is the answer for my question on there? Why it's duplicate? – Ramesh Rajendran Apr 17 '14 at 12:43
Because of how similar these two problems are, the right thing to do would probably have been editing… to say that this happens on all pages that have a long URL. – The Guy with The Hat Apr 17 '14 at 12:50
@TheGuywithTheHat: I'd make the other question a dupe of this one, since this one more clearly explains the problem. – Martijn Pieters Apr 17 '14 at 13:56

An overly long URL like that should probably be handled as a 400 Bad Request or 415 Request-URI Too Long.

You do get a 404 response:

$ curl -D - ""
HTTP/1.1 404 Not Found
Date: Thu, 17 Apr 2014 10:05:02 GMT
Content-Length: 0

But a 400 Bad Request or 415 Request-URI Too Long response body wouldn't hurt.

Yes, But why it's shown blank? Why it's not go to page not found screen? We need to so a error message to user – Ramesh Rajendran Apr 17 '14 at 10:10
"But a 400 Bad Request response body wouldn't hurt." He's agreeing with you @RameshRajendran. – Bart Apr 17 '14 at 10:12
@Bart , Yep. That is a bad request. but my question is Why the MSE and MSO does not show a message for that? – Ramesh Rajendran Apr 17 '14 at 10:18
bugs feed developers, those are put in deliberately... :-) – rene Apr 17 '14 at 10:27
@RameshRajendran: because bug, that's why. – Martijn Pieters Apr 17 '14 at 10:31
