We have built java based REST Webservices for the mobile app to interact with Sharepoint server. We are hosting webservices on weblogic server. Textual data is transferred in JSON format and file assets are transferred to iPad application as a binary stream. We are using HTTP GET to retrieve the file asset from the sharepoint. We have been noticing issues while trying to retrieve file assets which are greater than 20MB and only in production environment.
We are using Apache HTTPClient 4.2 as http client and apache commons IO library for IO copy.
Below is the code -
This is only happening in production and uat environments where we cannot have wireshark installed to debug this further. Have validated the sharepoint setting and weblogic settings and they are same as other environments.
