This PHP script returns compressed content, and a header which says it will return compressed content (using deflate, not gzip) is also sent back.

I can confirm that using LS 2.2.6:

powermac:~ gb$ curl -i "http://my.domain.com/dataservice.asmx/RequestProgramData?UUID=EGU7TZLA1JA94H679Z9WVV5ETE EG17&ProviderId=A_00001&DaysRequested=8"

...

Returning the same thing under 3.0 doesn't work, with Dynamic Compression On or Off.

I don't think LS should try to uncompress content if the script returns compressed content.
Enabling Dynamic Compression should only affect uncompressed content, which LS would try to compress before returning it to the client.

Thanks.
