Hi Everybody,
I have a problem that is driving me crazy and I am hoping for some help
here.
I am building an application (vb.net, vs2003) that crawls selected websites.
The application works fine except for one thing: Some sites rely on session
cookies and I don't seem to be returning the cookies.
The IIS5 log looks like this when I access the same page with
IE:
12:13:15 192.168.0.2 CLIENT GET /pm4/aboutus.asp - 200 71
Mozilla/4.0+(compatible ;+MSIE+6.0;+Win dows+NT+5.1;+SV 1;+.NET+CLR+1.0 .3705;+.NET+CLR +1.1.4322;+.NET +CLR+2.0.40607)
signinfrom=;+AS PSESSIONIDCAABT ABS=EMFHLDECGHE EOCJBFMLLMDFD;+ ASPSESSIONIDACA CQBBS=NMONBFECJ PICHEGFGACFEIJG
-
My Application:
11:40:42 192.168.0.2 CLIENT GET /pm4/aboutus.asp - 200 40
Mozilla/4.0+(compatible ;+MSIE+6.0;+Win dows+NT+5.1;+Q3 12461;+.NET+CLR +1.0.3705)
- -
As you see the session cookies are missing.
The relevant part of my code looks like this:
Dim req As HttpWebRequest = CType(WebReques t.Create(url), HttpWebRequest)
req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461;
..NET CLR 1.0.3705)"
req.CookieConta iner = New CookieContainer
req.KeepAlive = True
req.Headers.Set ("Pragma", "no-cache")
req.Timeout = 30000
req.ContentType = "applicatio n/x-www-form-urlencoded"
Dim ReceiveStream As Stream
Dim encode As Encoding
Dim sr As StreamReader
result = req.GetResponse ()
ReceiveStream = result.GetRespo nseStream()
encode = System.Text.Enc oding.GetEncodi ng("utf-8")
sr = New StreamReader(Re ceiveStream, encode)
etc...
If I access a .aspx page it confirms that my application supports cookies,
javascript, etc. It basically accepts that I emulate an IE.
But the cookie thing doesn't work.
What I am doing wrong?
Yours,

I'm trying to programmatically post data to another page within my ASP.Net

context, hidden fields, or anything else...I've exhausted all my other
options, so I have to get this scenario working). Basically, if I POST the
data normally, it works fine, except the target page has a new session ID,
so I lost the session data that I *do* transfer around. However, if I...

am ripping my hair out trying to divert an HttpRequest to a new location via

Hi,
I have a web app that I want to make calls back into itself (preserving the
session cookies etc).
I am using a System.Net.HttpWebRequest object to make the request, but I am
having trouble getting the cookies into it.
In the current (i.e. incoming) request, the cookies are stored as
System.Web.HttpCookie objects in a System.Web.HttpCookieCollection. However,

Hey Group,
I'm in the process of converting an ASP-based site to an ASP.NET site and
built a control that wraps around an ASP page. The control simply does a GET
to the same server to render the ASP content, and then just writes it to the
page.
In development and testing, there were no problems. Once deployed to
production, after the site runs for a few hours, it starts to slow down and
throw countless "Operation Has Timed Out"...

I am using HttpWebRequest to get the content of a web page. the call to

reads the session created on the 1st page. so when i call it with

I am trying to foward the old sessionID using "Session.SessionID" to
an HttpWebRequest CookieContainer so that I can capture the requested
page session variables but it is not working as it is supposed to. The
HttpResponse object always returns a different sessionID from the old
one which I am trying to force. Why is objRequest not carrying over the
old SessionID?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
