Try

After roughly 250 iterations of about 5-6 WebRequest per iteration, the app hangs and starts hitting the WebException "The remote name could not be resolved: 'hostnamehere' ". WebPages also don't load through my browser when this happens, I have to close the app for my internet to work again. This app is multithreaded and I was testing with 100 threads (in a threadpool, MaxThreadCount set to 20, addressof the sub which performs the WebRequests). A test with 20 threads yielded identical results - Same WebException also right around 250 iterations processing the same sub. I have tried setting the ConnectionLimit of the request to the thread count with no luck.

I am trying to implement the webrequest get and post methods. I am accessing a secure site that requires login authentication and was told that instead of sending a login request all the time; login to the site and capture the cookie and use this to send it in the header to get results from the page. In other words let us use google for example.
Lets say google required u to login before searching for something. Now I login through my browser and leave the site logged in. Now I send a httwebrequest from my program that includes the cookie authentication details in the request header and get results for say ?param=sports. Now when I increment the page number like &page=3, I am still only getting page 1 results. Here is some code:
[Code]...
I would like to search an online (internet) database and import the result in my own Windows program. As I understand from reading and searching I first have to do a get from the default (search) page to get the cookies for instance and then do a post providing the filled input fields and adding the previously collected cookies. So far getting the information seems to work but submitting the data back to get the actual search result doesn't seem to work. This is what I have so far: [code]Anybody that can point me in the right direction? I my assumption correct that I first have to do a Get and then Post the correct data back?
View 3 RepliesI think this is a simple question for you, but I don't understand other cases of webRequests, so I asked here: How can I make this webRequest asynchronous?

Dim oRequest As WebRequest = WebRequest.Create(url)
oRequest.Method = "GET"
Dim oResponse As WebResponse = oRequest.GetResponse()
Dim oStream As New StreamReader(oResponse.GetResponseStream())

View 1 RepliesThe current version of my application was using the WebClient object to download files from the internet and all was working well until some users reported that they were getting server timeouts. I looked into this issue and decided to move to the WebRequest object as it allows me to specify a Timeout value. The problem is, when using it synchronously, if I specify a timeout value of -1, I am worried that in the event of some weird server anamoly, my application would hang as it would be waiting for a response that isn't coming. So then I thought of using the WebRequest ansynchronously.

I am still learning about Get / Post statements in VB, and wondering if you have to call the Get commands to images, and what not, or just the main Post / Get statement and the rest will auto-load?

I have a loop with WebRequest objects which I declare every iteration. I thought it would be more efficient to declare them outside of the loop and only modify the one parameter that changed but it didn�t work. Why is that? It seems like the loop acts like a subroutine or other block that kills it�s objects at the end of each iteration. Is this the case? It seems other global objects like a text box can be modified this way so why not the WebRequest?

View 3 RepliesI am writing some rest calls to the LinkedIn API using web request and have hit an encoding issue.The LinkedIn API takes requires an encoded URI as one of the parameters on the lookup i am trying to run.
We are calling the api through .Net's WebRequest.Create; and when we pass in the URI it decodes it and as a result we can't get the data from the call.

I am trying to "behind the scenes" log myself into a website, from the VB code behind my ASP.NET website. But I am dumbfounded as to how to do this.
As far as I know I should be using the WebRequest or Webclient class. That is about as much as I know. I am not sure how to use the class.
I want to click a button on my website and have its Click event send a username and password to another website. This other site isot affiliated with mine. I realize the concept may seem stupid, but I plan on taking this further later, but Just need to know this now.
I made a small console program to login into a website.After figuring out on how to successfully login to the website i ran into a other problem... that problem is visiting the inbox page.The problem is as follow: when i visit the page i get logged out :sMy problem is i think that i don't know how to pass the cookie/session correctly since this is not a post/submit action...When i debug the site and click on the hyperlink i only get get response.
