Both outputs look similar to me. They're chunked transfer-encoded. If you're
using the output directly, your client is broken, as it's not decoding the
chunks, which IIRC is a required capability of any HTTP/1.1 client.

Chunk size here. Indicates it's 4,044 bytes long. Presumably this covers the
entire document in one chunk.

Chunk #1, 0x8d = 141 bytes.
>o;?<app><name>eek</name><author>Me</author><version>0.1</version><contact>Me@.com</contact></app>
Data for chunk #1.

Chunk #2, 0x2e = 30 bytes.

Data for chunk #2.

And so on...
If your client can't handle this, perhaps it should be making HTTP/1.0
requests.
