Need help with uploading large files through ASP Web Service

Question

I am uploading large files through ASP Web service. I tried running the program from my local server IIS and it works fine but, when I host it in a third party IIS server and try uploading around  25MB file I get this following error:

Unhandled Exception: System.Net.WebException: The request failed with HTTP statu

Answer 1

I had this error with a WCF service I am writing.  Although the answer did not seem logical based on the error message, it turned out that the problem had to do with the size of the data I was uploading through the service.  I am not sure where you would place this information in your case, but for me, I had to include a readerQuota setting in the binding tag.  Since I am still writing this service, I have not optimized this information.  I know that any file this large would probably timeout, but this is the line in my config file that allowed my service to function:

<readerQuotas maxStringContentLength="2147483647" maxArrayLength="163840000" />

Hope that helps!

Answer 2

Hi, I don't have a clue where to place this element because, intellisense feature couldn't recognise readerQuotas element unfortunately. I tried adding few lines:

<sessionState mode="StateServer" timeout="20"/>

and

this.Session.Timeout = 20;

These doesn't seems to work as well

Answer 3

Make sure your asmx web service accessible.

Make sure you have correct address configured on configuration file of asp.net’s web.config.

For large data, asmx web service provides two additional parameters you can configure

• maxMessageLength
• executionTimeoutInSeconds

<configuration>
  <system.web>
  <httpRuntime maxMessageLength="409600"
    executionTimeoutInSeconds="300"/>
  </system.web>
</configuration>

Refer http://msdn.microsoft.com/en-us/library/aa529330.aspx to configure this.

This forum is for WCF, You can post or move your question to ASMX Web Services and XML Serialization Forum where some expert can assist you.

Answer 4

The HTTP status 404 illustrates that the server has not found anything matching the URI given. you can set a breakpoint in the web method and debug it (in the debug menu, 'attach to process' to aspnet_wp.exe or w2wp.exe). if you want to upload large file using web service, you need to set the maxRequestLength and executionTimeout in httpRuntime appropriately and increase their values. Here is a article about uploading large files using web service.

Answer 5

The link which you have provided helps to uploadLarge files using FileStream which normally wouldn't support uploading large files. It could be done by splitting the bytes into chunks as how he has done but, on my case I have used File class which doesn't require such things. File class by default writes large files even if it is 50 MB. It works in my home but, it doesn't work only when I host it on the server.

Answer 6

Web Service is accessible and I am able to consume other services through that. The only problem which I am facing is this upload functionality. I tried my level to get this work but, I couldn't succeed in this. I'm able to upload 50MB files on my local IIS server but, I have hosted my service in godaddy hosting service and I couldn't upload large files only there. I believe it is the time out which is causing that issue because, I tried checking the time taken to reject the request and all the requests get rejected at the same time.

Answer 7

First you can increasing the value of maxRequestLength and executionTimeoutInSeconds in httpRuntime as mentioned above, and here is an additional item that can be added to the web service's web.config file to permit large file transfers.

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\ISAPI

 <location path="Copy.asmx"> <!-- Name of you asmx -->
     <system.webServer>
       <security>
         <requestFiltering>
           <requestLimits maxAllowedContentLength="104857600"/> <!-- 100 megs -->
         </requestFiltering>
       </security>
     </system.webServer>
   </location>

This appears to enable larger files to be uploaded via web services, For more about this, please check this similar post.
