问题 In one of my apps, I am getting the response from a webrequest.

HttpWebResponse won't scale for concurrent outbound requests

∥☆過路亽.° 提交于 2019-11-28 23:34:23
I have an ASP.NET 3.5 server application written in C#. It makes outbound requests to a REST API using HttpWebRequest and HttpWebResponse. I have setup a test application to send these requests on separate threads (to vaguely mimic concurrency against the server). Please note this is more of a Mono/Environment question than a code question; so please keep in mind that the code below is not verbatim; just a cut/paste of the functional bits. Here is some pseudo-code: // threaded client piece int numThreads = 1; ManualResetEvent doneEvent; using (doneEvent = new ManualResetEvent(false)) { for

How to get cookies info inside of a CookieContainer? (All Of Them, Not For A Specific Domain)

Please see the code below: CookieContainer cookieJar = new CookieContainer(); HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://www.google.com"); request.CookieContainer = cookieJar; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); int cookieCount = cookieJar.Count; How can I get cookies info inside cookieJar ?

Authentication failed because the remote party has closed the transport stream exception when getting a response from webservice

我怕爱的太早我们不能终老 提交于 2019-11-28 22:01:53
问题 I am calling a third party service and when I ask for a response it throws out an exception that says "Authentication failed because the remote party has closed the transport stream exception". I think that there is a problem in sending credentials. I have even tried supplying new credentials. Here is the full code string get_url = "https://**.*******.com/com/******/webservices/public_webservice.cfc?wsdl&Method=CreateUser&SiteID=**&WSPassword=******&UserName=******"; HttpWebRequest request =

How to parse HttpWebResponse.Headers.Keys for a Set-Cookie session id returned

耗尽温柔 提交于 2019-11-28 17:33:08
I'm trying to create an HttpWebRequest/HttpWebResponse session with an ASP.NET website to later parse an HTML form through url params (this part I know how to do), but I do not understand how to parse and set a cookie such as the session id. In Fiddler, it shows that the ASP.NET Session ID is returned through Set-Cookie in the response to the request to the / path of the url, but how can I extract this session id and set it as a cookie for the next HttpWebRequest? I understand that this Set-Cookie header would be found in HttpWebResponse.Headers.Keys, but is there a direct path to parsing it?

HttpWebResponse LastModified

问题 Is the HttpWebResponse.LastModified accurate? Is it always present? My project is to create a sort of a focused web crawler and I am stucked if I will use the hash value of a resource or just the HttpWebResponse.LastModified property to check the resource's "freshness". Using the hash value means streaming the resource every time it's checked. This has a big impact on overall performance. If I will just check the HttpWebResponse.LastModified, is it accurate? 回答1: HttpWebResponse.LastModified

HttpWebResponse returns 404 error

How to let Httpwebresponse ignore the 404 error and continue with it? It's easier than looking for exceptions in input as it is very rare when this happens. I'm assuming you have a line somewhere in your code like: HttpWebResponse response = request.GetResponse() as HttpWebResponse; Simply replace it with this: HttpWebResponse response; try { response = request.GetResponse() as HttpWebResponse; } catch (WebException ex) { response = ex.Response as HttpWebResponse; } try { HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://mysite.com"); HttpWebResponse response =

问题 I want to update something on my aspx page, after I send a file to be downloaded. (Some error messages shown before.). I believe it's not possible, but would you provide me a solution?

HttpWebRequest and HttpWebResponse shows old data

问题 After updating the data, when the webservice is called, it still fetches old data. New data is loaded only when I logout of the app and then login again. protected async override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e) { base.OnNavigatedTo(e); parameterValue = this.NavigationContext.QueryString["parameter"]; Uri UserDetailUrl = new Uri(Constants.WebService.ws_single_user + "?user_id=" + parameterValue); HttpWebRequest UserDetailRequest = (HttpWebRequest

I'm using Facebook Graph Api and trying to get user data.
