C# - How To Write HTTP Request Content To File Asynchronously
Dec 30, 2010
I am passing some data in HTTP body using the Ajax request. These contents on server are accessible using Request.InputStream. Now i want to write it to file on server disk Asynchronously. How to do that ?
If the data sent using the HTTP is more then i don't want server application to die/get affected. So that i would like to write it Asynchronously.
Following is sample for reference regarding what i am trying to do ...
System.IO.Stream str;
// Create a Stream object.
str = Request.InputStream;
// TO DO Write it to file asyncronously ...
str.Write(someFile, 0, strLen);
Reporting system has list of available reports on a web page. When user clicks on a report new browser window opens, server starts to prepare report (winword document) and then sends it back after 2-10 seconds.
Is it possible to send multiple HTTP requests asynchronously to an ASP.NET web site or any other web server using .NET ? And, then. collect responses from those requests as they come using .NET asynchronous paradigm ? Is it possible ? Or would there still be limit of max 2 HTTP connections from .NET using HTTP ?
I am working on an ajax application in which user can see chart (an image) of any available product. For generating chart I am using MS-Chart control. User will click a product link, its id will be passed to server side where image will be generated, returned to client side and displayed. All this is to be done asynchronously.
I thought to call a call web method, but what web method will return ?
I tried using HttpHandler but I did not get how to pass parameter (id) to it ?
When I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.
i redirect a page from http to https using http module begin request handler .i am calling webservice using ajax but it is saying webserice not defined .which otherwise works fineits work fine when rediect page in page_load instead .but i need to add function for https to http in every page. i still not know why ajax is not working when i use http module for redirect
I have an httpmodule and it has a handler for OnEndRequest. I am trying to write the HttpContext.Response.OutputStream to a file. I am trying to use the Read method of it. But when it is called the exception message i get is "Specified method is not supported". So i am not able to do what i want that is, write the response to a file on the disk. I am able to write the HttpContext.Request.InputStream to a file using its Read method which i do in a handler for OnBeginRequest.
I have a webservice which works 100% fine on my developer machine. Where Web Service is installed on LOCALHOST on my developer machine,Then i went to my servers, I installed webservice on one server and map it with the server where the website is hosted, Then i tried accessing this service using BROWSER from my web server, it worked fine, That means the mapping was done perfect.Then i run my program on web server (website). It worked fine on page1, then on page2, but when i did the same and call same function on page3, It popped me any error of
I there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.
public void Init(HttpApplication context) { context.AuthenticateRequest += new EventHandler(AuthenticateRequest); } protected void AuthenticateRequest(object sender, EventArgs e) { app = sender as HttpApplication; if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) { // a few requests do not enter here, but my webservice class still executing // ... } } I have disabled HTTP POST and HTTP GET for webservices in my web.config file. <webServices> <protocols> <remove name="HttpGet" /> <remove name="HttpPost" /> <add name="AnyHttpSoap" /> </protocols> </webServices> Looking at ContentType for soap+xml only partially solves my problem. For example, Cache-Control: no-cache Connection: Keep-Alive Content-Length: 1131 Content-Type: text/xml Accept: */* Accept-Encoding: gzip, deflate Accept-Language: ro Host: localhost mymethod: urn:[URL]
Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).
I develop an asmx web service (i.e. ASP.NET 2.0). There's a piece of code that may read the contents of the HTTP request (via HttpContext.Current.Request.InputStream) while processing it. I realise that InputStream may only be read once for a request, and I make sure I never try to read it more than once.
The problem seems to be that if InputStream happens to be read during the early stages of the application's lifecycle (e.g. after pskill w3wp, during Application_Start), the HTTP request fails with a HTTP 400 - Bad Request error, with no explanation given, no exception thrown and no entry in the httperr log. If it is read later (e.g. within the web method itself), requests run fine whether InputStream is read or not. Application_Start runs fine if InputStream isn't read.
Is this some sort of ASP.NET bug? IIS bug? Or am I doing something wrong by daring to read InputStream? And if so, is there another way to get a look at the "raw" contents of the request without disturbing the inner workings of IIS/ASP.NET? In short, adding this code within Application_Start is enough to reproduce this error: using (StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream))reader.ReadToEnd();
I am trying to write a file to a network drive from my asp.Net application and i get this error - Logon failure: unknown user name or bad password. I am able to write to a local drive line C:/temp But when I try to save the file to a network drive such as ServerFolder, I get the error mentioned above.
MyMasterPage.aspx and content page MyDefault.aspx. MyMasterPage.aspx has one input button [value="Menu-1"]. When user click the button, the button will pass value "Menu-1" into TextBox1Default1 at content page MyDefault.aspx, and then refresh UpdatePanelDefault1 at content page MyDefault.aspx asynchronously.
My problem is the post back is full post back when refreshing UpdatePanelDefault1. I would like asynchronously post back during refreshing UpdatePanelDefault1. copy the full code MyMasterPage.aspx and MyDefault.aspx below, and then paste / overwrite it into your blank aspx page for testing. I am using VS 2008
I'm trying to write an HTTP GET handler. The path should start with http://site/processTask and have a set of URL-encoded parameters. I have the following in my web.config
now when I type the URL http://mysite/processTask in browser I get HTTP 404 but if I change the add verb line to the following one:
<add verb="GET" path="processTask.asmx*" type="MyHandler.ProcessTaskHandler, MyHandler"/> and type http://mysite/ProcessTask.asmx in browser the handler is run and I get the response from the handler. What's the problem? Why is the handler run only when the path contains .asmx? How do I change web.config so that .asmx is not required?
It uses asp.net (webforms), bunch of jquery plugins and whatnot.
Problem: there's unnecessary HTTP request to localhost/undefined and that makes every request take ~1s longer than needed.
Question: is there any tactic to find guilty code?
Clue: undefined makes me think that there's JS involved.
Firebug log:
GET /undefined HTTP/1.1 Host: localhost:17817 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; lv; rv:1.9.2) Gecko/20100115 Firefox/3.6 Accept: image/png,image/;q=0.8,/*;q=0.5 Accept-Language: lv,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-13,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://localhost:17817/Default.aspx
if you right click a line in the code, it gives you a conditional breakpoint. Check the name of the variable that has the URL value, and set a condition when typeof URL === 'undefined' or url === 'undefined' and look at the stack
Just set breakproint at line 3400 (with no conditions). It does not go through there.
3397 ajax: function( s ) { 3398 // Extend the settings, but re-extend 's' so that it can be 3399 // checked again later (in the test suite, specifically) 3400 s = jQuery.extend(true, s, jQuery.extend(true, {}, jQuery.ajaxSettings, s));
Narrowed issue down a bit => commented out 1 ascx controller that renders some images and uses gallerific jquery plugin and magic request dissapeared.
Problem was with galleriffic plugin initialization. It couldn't find anchor and it's href for creating thumbnails when there were no images or something. It's cool now...
I am using C# + VSTS 2008 + .Net 3.5 + ASP.Net + IIS 7.0 + ADO.Net + SQL Server 2008. I want to develop an ASP.Net aspx page which has the following function,
1 It could accept 3 Url parameters param1, param2 and param3, and the request looks like this,
2 When the page is responsed to client browser, I want to display a text input and a submit button nearby in the result html page, and value of text input is the same as param1, in this sample, abc will be displayed in text box, in the browser address bar, I want to keep the original long url http://mysite.com/foo.aspx?parame1=abc¶m2=def¶m3=ghi;
3 When the user change the value in text input, and click submit button, I want to send this request again to foo.aspx, and changing the param1 value to the value which user entered in text input, and at the same time, keep values of parame2 and param3 the same as last request's response. For example, when user requests http://mysite.com/foo.aspx?parame1=abc¶m2=def¶m3=ghi, and the page displays, when user changes text input from abc to google, the new request will be http://mysite.com/foo.aspx?parame1=google¶m2=def¶m3=ghi
Any reference samples? My question is I do not know how to implement so many functions in one aspx page.
I need to I can make the web request to a webservice which take a XML argument. And is expected to return a Binary response.

When I read the response using streamreader see the header and some attached "HEBRISH" words probably binary but unable to sepreate it out. Please help in seprating out the binary the response data.
how do u handle dates in mvc when request is a http GET? I remember some discussoin on this last year but cant find the posts.. things like culture unaware, splitting the date field to 3 text fields insted of 1.
I'm currently trying to setup testing with Selenium. It seems that Selenium sends a HEAD request to my route /Home/Index before it sends the GET request. This causes all my tests to fail. I was wondering how I would go about getting HEAD requests to respond correctly (not 404).
