c# - Uploading file to Web API timeouts on the server -

i've been having problem day, , i'm pretty lost why happens.

i'm posting file (a .xls file) client side in react js component in response click on button this:

upload: function (e) {     e.preventdefault();     var model = this.state.model;     var xlsfile = this.refs.xlsfile.getdomnode();     var file = xlsfile.files[0];     var fd = new formdata();     fd.append('file', file);     var request = {         groupid: this.state.vknumber,         payload: fd     };     model.importrequest = request;     model.setimportprocessing();     multiorderactions.updateusers(request);      this.setstate(model.tostate()); } 

the request appears in chrome (post-request):

accept:/ accept-encoding:gzip, deflate accept-language:en-us,en;q=0.8,da;q=0.6 connection:keep-alive content-length:3799243 content-type:multipart/form-data; boundary=----webkitformboundarybvyydsxrza1yruw4

and payload of request:

------webkitformboundarybvyydsxrza1yruw4 content-disposition: form-data; name="file"; filename="bruger_caas.xls" content-type: application/vnd.ms-excel

------webkitformboundarybvyydsxrza1yruw4--

should there not binary data in request? content length correct, , content-type , filename.

in webapi i'm doing following, readasmultipartasync never returns:

[httppost]     [route("bc/s/{*url}")]     public async task<ihttpactionresult> post(string url)     {         var service = createclient<genericservice>();         if (request.content.ismimemultipartcontent())         {             try             {                 var provider = new multipartmemorystreamprovider();                 await request.content.readasmultipartasync(provider);                  foreach (var content in provider.contents)                 {                     //do stuff                     ;                 }              }             catch (exception e)             {                 ;             }         }          return internalservererror();     } 

when reaches await keyword dies, , times out after 2 minutes, because chrome cancels request.

what doing wrong here? i'm not sure if problem file never sent client side, or if it's server side code that's problem.

any input appreciated.
