Tapatalk Android client.


On launch, Tapatalk sends a big chunk ~16KB of data using POST. Captured request looks like below. pixelserv-tls v2.0.1-rc2 crashes.

POST /v2.9/469687153111700/activities?access_token=&format=json&sdk=android HTTP/1.1

Tapatalk uses multi-part POST to upload contents to pixelserv-tls (i.e. ad servers) with Transport-Encoding: chunked. pixelserv-tls cannot parse this mechanism and hence crashes.

Fixed crash with 0063f766

Full support of Transport-Encoding: chunked need more work and has to wait in a future release.
