Two .axd handlers, one is working and the other one returns 404

Question

I have 2 custom .axd handlers in my project. Both defined in web.config under httpHandlers and handlers:

httpHandlers:

    <add verb="GET" path="ShowImage.axd" validate="false" type="ImageServer.StreamImage, ImageServer"/>

  <add verb="GET,POST" path="Upload.axd" validate="false" type="UploadFileServer.UploadFile, UploadFileServer"/>

handlers:

    <add name="ImageServer" preCondition="integratedMode" path="ShowImage.axd" verb="GET" type="ImageServer.StreamImage, ImageServer"/>
  <add name="UploadFileServer" preCondition="integratedMode" path="Upload.axd" verb="GET,POST" type="UploadFileServer.UploadFile, UploadFileServer"/>

when I call ShowImage.axd everything is working fine.

The request in fiddler looks like:

GET /WebApp/ShowImage.axd?Bla=x HTTP/1.1

when I call Upload.axd, I get 404.

The request in fiddler looks like:

POST /WebApp/Upload.axd HTTP/1.1

Both .dll's are in the Bin folder.

why?

Answer 1

Can you please post the code how you are calling the Upload handler. Till then try making your upload hander use only "POST" verb and see if it works.

<add verb="POST" path="Upload.axd" validate="false" type="UploadFileServer.UploadFile, UploadFileServer"/>
