As per this question, I need to make something clear:

Opera Mini does support compressed data.

Don't believe me? I went to http://www.ericgiguere.com/tools/http-header-viewer.html with my phone and sure enough:

Accept-encoding: deflate, gzip, x-gzip, identity, *;q=0

Still don't believe me?

See here:

I hope that this makes it quite clear who supports what. If you want to give me a URL and have me visit it with my phone to verify this, I would be happy to.

Update: the headers above are from the Opera Mini proxy server, not my phone. When Opera Mini visits a page, my phone connects to their 'turbo' proxy, which in turn connects to stackoverflow.com. When the proxy connects, it fetches data with the above headers - indicating that it supports compressed data.

Your a programmer aren't you? Just make your own web browser and quit whining that Opera Mini isn't supported –  Earlz May 2 '10 at 4:02

@Earlz: You think it's easy to create a J2ME browser with built-in compression, compatibility with thousands of phones, and a massive server farm encoding pages for it? Gimme a break. –  uɐɯsO uɐɥʇɐN May 2 '10 at 4:43

You misunderstand.

Opera routes a lot of their "mini" and "mobile" requests through a compressing service they call "turbo". This is a kind of proxy.

This compressing services requests all HTTP data in uncompressed format, which it then compresses (using "max" compression) and returns to the browser. This is completely nonsensical and even a little ironic, since it uses tons of bandwidth .. sort of the opposite of turbo. Anyway, it could

retrieve compressed -> decompress -> recompress

just as easily as it could

retrieve uncompressed -> compress

The IP addresses of this poorly designed proxy are banned. If you can get the browser to correct DIRECTLY to our website from YOUR IP address, you won't be banned.

Take it up with Opera, Inc if you have an issue with this; from my perspective their proxy is banned forever until they fix the behavior.

And of course Jeff beats me by a few seconds lol –  MrStatic May 2 '10 at 1:28

Their proxy is requesting data compressed. See the picture above. These headers are from their proxy server. The route the data takes after their servers have it is irrelevant to this discussion. –  uɐɯsO uɐɥʇɐN May 2 '10 at 1:30

as far as I'm concerned this just another in a long string of idiocy from Opera. They need to either stop making web browsers, or adopt WebKit as their engine. –  Jeff Atwood May 2 '10 at 1:30
    
Well... webkit is a good idea. I'll agree with you there. –  uɐɯsO uɐɥʇɐN May 2 '10 at 1:31

@Jeff: The headers above are from the proxy. Not my phone. –  uɐɯsO uɐɥʇɐN May 2 '10 at 1:33
    
You mention that 'it could retrieve compressed -> decompress -> decompress just as easily as it could retrieve uncompressed -> compress'. This is not true. Opera Mini uses a proprietary format to deliver content from their servers to the phones called OBML. It's not gzip. –  uɐɯsO uɐɥʇɐN May 2 '10 at 1:59

@George: so they could retrieve compress -> decompess -> compress into their proprietary format, then. –  Ether May 2 '10 at 2:05
    
No... when their proxy server retrieves gzip data, there is no simple way to convert that to their OBML format. They would have to decompress and recompress. –  uɐɯsO uɐɥʇɐN May 2 '10 at 2:08

@George: That's exactly what Jeff said... what are you getting at? –  James McNellis May 2 '10 at 2:10

@James: Oh right... I misunderstood. BUT they still are sending accept-encoding headers that suggest compressed data is accepted. –  uɐɯsO uɐɥʇɐN May 2 '10 at 2:13

I think you should stop whining, as Jeff will never unban it, so forget about it (and try jQuery) @george –  jmfsg May 3 '10 at 1:58

@Downvoter: it isn't totally banned anyway - I'm using it right now. Nobody is complaining about that, are they? –  uɐɯsO uɐɥʇɐN May 3 '10 at 3:58

Come on George, you can say it: "I designed the Opera Turbo proxy" ;)
