I have a device with an embedded webserver that accepts URL-based commands and queries. The device provides a user-privilege schema, so I have administrative accounts, operator accounts, and plain user accounts. Certain commands and queries require authorization via username and password to establish the privilege level available.

The target server is writen in Cold Fusion and i have no access to there.
In addition i get only this error msg: The remote Server returned an error: (500) Internal Server Error
What can i do in order to come with a more friendly exception message?
Am i overlooking something obvious in my code? myResponse.Close()
This is the short instruction:
1) Make a single HTTP-POST request to the following URL in XML format.
[URL]={password}&user={username}
2) The xml form field that is posted should be named "createorder".
I don't get the last part with naming the xml form field. What the xml form field means (stands for) in this context?

I'm looking at a website using Internet Explorer and Firefox. In each browser I select view source and see the website's URL in the links. These links were concatenated together using HttpContext.Current.Request.Url.Host in the code behind. However, when I use netcat or Burp Suite v1.3.03, looking at the same links I see the servername instead of the website's URL.
My question is - Why does view source in the browser display different links in the page source than what netcat or Burp Suite outputs? Is the browser rewriting stuff? My thought to correct is to have a web.config setting which is used to create the links. Next question - Does anyone know of a configuration change to make to IIS to return the URL instead of the server name or a .NET function that I should be calling instead to get the URL that the website is running as.
I have following function:
in a.aspx.vb page:
If a = True Then
'do something
Else
'i want to show a not authorized page here
End If
Will i have to create a new page and give the url under else to show not authorized page? Or is there any other pre-built way to do this in .net 4.0?

View 2 RepliesI use web methods in a couple of places in the intranet site im working on and they work fine, however one page is constantly throwing a HTTP 401 error every time I try access the web method.
Im not sure how to aproach this issue, I have tried commenting everything out of the web method, and still get the 401 error, even a basic connect to the database just doing SELECT 1 does not show up when I watch the DB with profiler.
My web.config is the same for all pages in the intranet and I cannot see any differences in my ASP.Net page compared to pages where web methods work.[code]...

I am facing a strange problem with listbox. I need to scrab whois information. I used the following code to get source code of the whois query. It works fine if I use a textbox. But I need to use this for multiple url and therefore need to use lixtbox to loop through url list. Unfortunately when I use listbox1.selecteditem or listbox1.text it does not work. But this same code works with webbrowser.
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("http://www.networksolutions.com/whois/results.jsp?domain=" & listbox1.selecteditem)
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705)"

I'm building this class to download files in parts/sections/segments. In .NET 4.0, I can use this code to specify the range to download from
long startPos = int.MaxValue+1;
HttpWebRequest.AddRange(startPos);
and it works because there is a long overload for the AddRange method. When I looked up the .NET 3.5 version, I realised the AddRange() method allows using int only. The possible workaround would be using the AddRange(string, int) or AddRange(string, int, int) methods. Since the class will have to work in .NET 3.5, I'll have to go with the string specification but unfortunately I can't seem to find any sample code that shows how to specify ranges using this procedure in .NET 3.5. Can anyone show be how to do this?As the first code sample I wrote shows, I would like to specify a range of type long instead of int. Using type int allows requesting for byte ranges only up to 2GB but long allows requesting for byte ranges beyong 2GB.
The question therefore is: How do I specify byte ranges of 2GB or higher on HttpWebRequest in .NET 3.5?

how to write a httpwebrequest, however i'm unsure of how to write it with a if...statement. I have a file that I need to download, however it ususally doesn't get posted until sometime Tuesday afternoon, so what I need to do is have the program continually check say once about every 5 minutes until the file has been posted and then download it.I'm presumming using an if...statement is the best way to accomplish this, basically if true(file exists) then proceed, else wait 5 minutes and rerun process.
