If on the other hand, the URL was for a webpage eg. You can use the class to determine the phone's current state. My installing the module before WSFederationAuthenticationModule I can assure that Request has already got a chance to cache the appropriate BufferlessInputStream before WSFam has a chance to screw it up.

I am trying to upload files using similar approach in windows phone. I used the diagnostic tools to monitor the memory consumption and noticed that memory grows exponentially during PostAsync call. Seems like it is copying the entire content to the memory. Right now we don't have chunking support in the api. What is the best strategy to upload large file using HttpClient in a low memory windows phone device? Do multipart POST manually - without help from MultipartFormDataContent If you must send it multi-part, then you could POST it more , reading from the source file in 4k buffer blocks. You don't necessarily need to do so with async methods. Here's another recommended link to understand how to. And another for understanding the protocol, here's an example of what gets sent out over the stream, Also, architecturally, I tend to prefer uploading files separately to any form data. This avoids multipart posting completely, making your APIs atomic and simple. You may have a service which simple stores an uploaded file and returns the URL or ID. That URL or ID can then be referenced with your data and posted subsequently. That link doesn't relate to multipart, and may confuse your manual implementation if you start with their async architecture. You should start with my link, and learn from your link to apply the asynch methods. There are many ways of implementing a manual 4k buffered POST multipart stream, but my overall answer is essentially to do it manually and give up on MultipartFormDataContent. Then send the other blocks and reconstruct it on the receiving end. EnsureSuccessStatusCode ; } } perhaps something like that would solve your problem :.

HttpWebRequest in C My described a method of sending a file and some data via HTTP multipart post by constructing the HTTP request with the class before writing the contents to the class. It was exactly what i was looking for to upload caballeros from my Phonegap application to Webapi using Azure. Background The concept for this solution is very simple. For the last handler, you can set the inner handler to an HttpClientHandler instance — this will pass the request on to the HTTP stack of the OS. This isn't asynchronous, and because it's a potentially lengthy operation could result in noticeable delays. Thus, a cookie received via a server response to a Syndication API call in the past might be added to a subsequent HttpClient request to that same server within the same app container. If the con should not be buffered like ourshttpclient download large file c# uses the good old HttpRequest. For example, it allows chaining custom handlers, by which developers could intercept each request or response, and implement custom logic.
