Binary files (e.g. png images) are clobbered on response

Example:

http://CSD:password:liberia-staging.mhero.org:5001/static/USAID_CP_IH_PEPFAR_logos.png

Should return the image here:

https://github.com/openhie/openinfoman/blob/master/webapp/static/USAID_CP_IH_PEPFAR_logos.png

which has file length 93730,but instead returns a file of length 174504.

Looking at the hex representation, it seems that (starting a offeset 0) we have:

89 50 4E 47 0D 0A 1A 0A 00 00 00 0D 49 48 44 52 00 00 03 92

becomes:

EF BF BD 50 4E 47 0D 0A 1A 0A 00 00 00 0D 49 48 44 52 00 00 03 EF BF BD

maybe is is a UTF-8 encoding issue?

Note, I am not sure if this also affects incoming binary data to OpenHIM. As you fix this bug, would you mind adding a test case to check incoming as well. Thanks!

Thanks Carl, good point. We will check this out. Btw, if you guys would like to work on these, feel free to submit PRs.
