Simultaneous uploads behind the proxy

Question

In AIR application, I am uploading two files simultaneously using FileReference.upload(). It works perfectly fine on all operating systems in most of the cases but in some cases doesn't work e.g when auto detect proxy option is checked on Mac OS. Although for FileReference API, it is documented that you must upload files one by one but it works really fine in most of the cases.
In debug proxy, it shows same request on both connections and one connection is in wait state. Did anyone encountered this situation? and know whats the root cause of this error? As a workaround, I tried determining upload mode (simultaneous/sequential) using two dummy files, but it is really random. sometimes two files are uploaded successfully and in some cases IO error is thrown after a long time.

Answer 1

Have you configured the proxy settings in Eclipse? I believe the SimpleProxyServlet uses the Eclipse Authenticator, and you can configure the proxy username and password in Eclipse.
SAPUI5 SDK - Demo Kit
Internet Servers
TheSimpleProxyServletcan be configured for proxy requests to internet servers in the same way as for intranet servers. Additional proxy settings may be necessary.
As theSimpleProxyServletautomatically uses the proxy settings from your Eclipse this can be configured in Eclipse under Window Preferences , and select General Network Connections . Here you can specify the proxy entries and the proxy bypass.
For example, set Active Provider to Manual, Schema=HTTP, Host=proxy, Port=8080 under proxy entries and localhost, *.sap.corp as Host under proxy bypass.
