Confused with Recurring Error

Ian Ryder · September 19th, 2012, 09:25 AM

Hi All,

I have developed my website after completing my study of Imar's book on Beginning ASP.NET 4.

The only thing that I still have not grasped is why I constantly get errors every day, reported by my website, as to pages that do not exist?

As an example I get (I do not expect anyone to read all of this):-

Quote:

Message
The file '/Campaigns/Security/CreateNewUser.aspx' does not exist.
Stack Trace

Query String

This page has NEVER existed in this path but it does exist in the correct path of ~/Security/CreateNewUser.aspx? This error is not just specific to this page but occurs with various pages that do exist in various different locations???

Please do have a look at the site Bionature UK Ltd (sorry, don't mean to push people to my site but a bit of marketing cannot be a bad thing) and you will see that you do not get any errors when browsing to any page.

So my question is does anyone know why this error is occurring?

Hoping for an answer.

Hi Ian,

Take a look here:

http://bionatureagriculture.com/Camp...2/Default.aspx

Then try to register with the link at the top. You're taken to Campaigns/Security/CreateNewUser.aspx which results in a 404

My guess is that the Register link (in a Master Page?) uses a relative link, not a root relative link. Change it to ~/Security.... (and if necessary, add runat="server to the link) and the problem is probably fixed.

P.S. Congrats on the site. Looks great!

Cheers,

Imar

BTW: you may need to change your error pages stratgey a bit.

If I request the page that cannot be found, it returns a 200 OK status. That page in turn requests a CSS file that doesn't exist. Setting the proper redirect type and status code as explained in the book should help.

You can use a tool like Fiddler (http://fiddler2.com) to see response codes.

Cheers,

Imar

Hi Imar,

Good to hear from you again and I hope you are well.

YOU ARE A STAR!

I cannot believe that I missed this simplest of errors on my part. I have applied the fixes that you pointed out and I can confirm that this has indeed fixed the problem. All I need to do now is go through each page of the site to find all the instances where this fix needs to be applied.

Thanks once again Imar and I am glad that you liked the site. Still quite a bit left to do but that would not have been possible without you and your book.

Take care Imar, keep up the good work and talk to you again soon.

Kindest regards,

Ian.

Isn't the register link inside a Master Page so you would have to fix it only once?

Hi Imar,

The small point that you must have missed is that I am also getting this with various other pagess on the site so I have obviously made the same mistake in other pages - already found another two. By the way, yes the register link is inside the master page.

Cheers,

Ian.

Ah, I see. Thanks for clarifying that.

Cheers,
