Subject Re: unsupported compression issue seen in 2.3.5-alpha
Date Mon, 15 Feb 2010 09:11:29 GMT
I don't know if this is connected, but we experience some problems
with gzip compressing.

Open http://www.micex.ru via Chrome and and hit shift + refresh
button. Sometimes tables will not load (a little rotating circle will
appear).
These tables are loaded via AJAX and when they are not loaded, Chrome
shows some garbage after JSON result. This garbage happens very often
in Chrome.

Some debugging showed that web server answer "with garbage" and
without differs in 20 bytes at the end. But only Chrome and some
Delphi libraries return error when extracting these archives.
Firefox, gzip console utility, they open it without problems.
