As you might notice (Last-Modified: Fri, 29 May 2015 14:22:44 GMT) the file hasn't been modified since the last request.
So I don't get why the response isn't a 304 status: not modified.
I'd really like to know why the caching of this files (and some others) doesn't work as I expect it.
It is bug in Apache. Turn off mod_deflate.

i dont know how to use httpwebrequest to login to the site with my account ?
See the example here:

your post data is: username=GMAL%40gmail.com&password=PASWW&remember=yes
Note: You are sending plain text password over http. If there's an https option you should use that.
Sometimes my IIS server starts responding with 304 HTTP status to non-conditional requests. I have yet to determine exactly when this happens, but when it starts all browsers keep getting 304.
This is the request (debugged using fiddler):
GET http://www.example.com/aaa/bbb/GetStaticResult HTTP/1.1
Host: www.example.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0

Accept-Encoding: gzip, deflate
Referer: http://localhost:12345/xxx
Origin: http://localhost:12345
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
And the response:
HTTP/1.1 304 Not Modified
Cache-Control: public
Expires: Thu, 30 Apr 2015 09:23:22 GMT

Server: Microsoft-IIS/7.5
X-Powered-By: ASP.NET

The ASP.NET MVC method is the following:
[HttpGet]
[OutputCache(Duration = int.MaxValue, VaryByParam = "")]
public string GetStaticResult()
{
return "static";
}
The request hasn't any If-Modified-Since (or similar) header. Shouldn't the server issue a 200 response?
May be related with Getting a 304 if there is no If-Modified-Since sent?
Using the Chrome network panel, I find that I have one request which keeps returning as 16027.6 days long. Considering how that's longer than my entire life so far, that seems excessive.

I'm not sure exactly what my web server is doing to trigger this, so I'm thinking this might be a Chrome-specific bug. Thoughts?
Looks like a time issue. Check the date on both local and remote machines. That response time is pretty close to the days since epoch which would indicate for some reason the server thinks it's 1970.
If you go to http://www.epochconverter.com/ copy the epoch time at the top (something like 1384805814), enter it in "Convert seconds to days, hours and minutes", you will get something like "16027 days, 20 hours, 16 minutes and 17 second" which is pretty close to what you're seeing in the console.
It's strange, though, to see Date in the response headers as correct and at the same time an expire for sometime in 1981...almost as if webserver is using one date and php is using another.
The solution will depend on what the stack you are using is. https://serverfault.com/ would be a better place to ask for help with the issue.

My code can login many site but with this site it doesn't work.
This part is a unique code that is generated on the Login page by the looks of it:
xid_d9db5=21e18e3615c5ed2ef0597789bcd74746
Scrape the above field & value & add it to the POST request instead of adding the exact code above to your request.
(You may also want to hide your POST data a bit more carefully incase you use them details elsewhere!)
