I'm trying to port an old VB.NET application to an Android application, but due to my lack of Java experience I am unable to find this one out. I have tried multiple solutions but to no avail.The idea is basically to do a POST request to 'url...' and getting the response cookies.[code]
View 2 RepliesWhen you search on google most of the examples are very vague, hopefully this thread can make it to the top and will help someone looking for the same info.to explain the code what it does is create a long string by concatenating all the values together stores it in the variable finalString and then hashes the string using the SHA5 algorithm. Then its supposed to send the string (finalString) as a post request to the url.The server im sending it to reads it this way and sends a response. [code]

View 1 RepliesI have two web servers with public IPs, for example Server1 with IP 111.111.111.111 and Server2 with IP 222.222.222.222. see the picture:
There is an asp.net webform at Server 1. My intention is:
For every http request to that webform in Server1, the Server1 just pass the request's information to Server2 for logic processing and subsequently Server2 sends the response back to client (i.e. normal browser)
My questions are:
What information that Server1 needs to pass to Server2, so that Server2 able to send response back to client? note that at Server2, there is a TcpListener instance. This TcpListener instance acting as receiver for that webform request information from Server1. What is the suitable object (i.e. the class in System.Net or related namespace such as System.Net.Sockets) at Server2 for sending response back to client? Suitable here means able to meet my intention.
How can I send a POST HTTP request to a server (in Visual Basic 2010) and then receive the reply into a string.

I am trying to write this program that logs into this website. Now I figured out how to make the http "POST" request to the specific spot on the page which returns a "Successfully logged in" afterwards but once I make a request to another part of the page, it asks me to login (I look at the source code). I have been messing with Fiddler and I compared the a POST from my webbrowser to a POST from my program. I found the following lines to be in my browser POST and not in my program post:

I am assuming this has something to do with the cookie that I am suppose to get to be able to tell the website that I am logged in. If someone could point me in the right direction that would be great. I dont use XMLHTTPREQUEST in my program. I found it earlier on the msdn website but now I cant find a reference to it.I am also not good with term names and I just started learning VB and don't know much about cookies/HTTP requests and such, but that is why I am trying to learn.
We have a number of classic ASP websites using a VB6 DLL (COM) object for their functionality in the standard way. The DLL is regsvr32'd and the pages use Server.CreateObject to create an instance of the necessary object in the DLL, which in turn triggers the OnStartPage function of the object being created, passing in the ScriptingContext which we then use to get Request(querystring, form) information, read/update session information and read/write cookie information (etc). For clarification, the way you update/store a cookie value using ScriptingContext is
objSC.Response.Cookies(Key) = Value
In preperation of doing a complete .Net overhaul on the code base (and as a first step), we ran the code through the .Net 2008 VB upgrade tool, which makes a few minor code changes, sets up references to interop libraries (for ADODB, ASPTypeLibrary, CDO, etc) and adds the necessary attributes to allow the .Net object to be exposed to COM, and after a few tweaks here and there guided by comments (todos) left by the upgrade tool, the code is compilable except for anything that tried to update/store a cookie using the above code as now, through the ASPTypeLibrary (Interop), the Response.Cookies collection is readonly (with no obvious way to write a cookie now).
If I comment out the offending line of code, the code compiles, and all I need to do is register this new .Net DLL (and it's interop DLLs) in the GAC, use regasm to register it through COM and the classic ASP sites continue working as if nothing happened (except for writing cookies), using Server.CreateObject to create what it thinks is a COM object, triggering the call to OnStartPage, passing in the ScriptingContext.So although the code base is "upgraded" to .Net it is using a lot of interop libraries to continues working as before, including using the ASPTypeLibrary.ScriptingContext object, as this is what the classic ASP pipeline exposes. how to write/store a cookie in this scenario?
I have the following method that creates a cookie in the page's response. Immediately after I create the cookie, I checked to see what the value was and it was blank. Is this normal behavior? How can I check the response for a cookie after it has been added?
When I monitor the HTTP response, the cookie is there. When I use the Firefox Web Developer Toolbar to view the cookie, it is there. However, it doesnt appear to be present in the Response.Cookies collection. How do I access it?
Dim c As New HttpCookie("prpg")
c.Expires = DateTime.Now.AddYears(10)
c.Value = value

I am sending xmlhttp request to a web server with parameter, and wait for the response before I send another request. About 98% the application is working fine, except if the internet speed became suddenly slow or there is a delay from the web server i am dealing with.

Public Class Test

My requirements are just created the sequence using VB.NET code and of no database help. The sequence must be started at 1 and incremented by 1. My attempt to solve this is by using STATIC variable within the Page_Load which can retain the sequence value.But someone told me that my approach is risky because it's not thread safe. Is that true? Or how do I create a sequence for each request that is free from any problems be it thread safe or others?
UPDATE: I attempted to solve the problem another way. But I'm not sure the thread safety of my new solution. Here is my code, the call to Singleton.Instance.Sequence function will generate a new sequence value:
Public NotInheritable Class Singleton
Private Sub New()

The rules are that the body format should be XML(values must be XML-escaped), HTTP Method (post), requires authentication(yes), request content(content-type: "application/xml". [code] Best practice is to incrementally add and remove changes to your entry list instead of deleting/recreating the entire list each time a change is necessary.New entries are placed at the top of the queue for polling and are processed in a LIFO manner.
