Question

I am using Apache mod_deflate to return compressed html from a webpage. It has reduced the generated page size from 3k down to 700 bytes.

How do I use HttpConnection in Blackberry to get the compressed page (i.e. only 700bytes instead of 3k)?

P.S. Trying to use the GZIPInputStream(inputStream) keeps returning an incorrect header check error.

Was it helpful?

Solution

As I understood you already tried to download and got non-compressed html page.

If so I think you should add "Accept-Encoding" header to your request (question on forum). Try:

connection.setRequestProperty("Accept-Encoding", "gzip, deflate");

Don't forget that you will get zipped data, so you need to unzip before using.

Also, as mentioned here, gzip/deflate is not so efficient when your traffic is going over BIS-B, BES. Because BB servers will encode/decode data to analyze it and make it more efficient fro transmission.
