Hi,
I am using a .NET Compact Framework 3.5 client that talks to server (Apache 2.2 shared module) which talks to database.
My client will sometimes retrieve large amount of data in a server call. So, I am using AutomaticDecompression on client and I have enabled gzip, deflate on Apache. However, if I try to fetch large amount of data, I will get the error:
| Code: | | "An existing connection was forcibly closed by the remote host" |
I am not finding anything in apache logs showing this error, it is showing on my client app.
Here is my GetWebRequest() method on client:
| Code: | protected override WebRequest GetWebRequest(Uri uri)
{
HttpWebRequest req = (HttpWebRequest)base.GetWebRequest(uri);
byte[] credentialBuffer = new UTF8Encoding().GetBytes(Settings.Get("usr") + ":" + Settings.Get("pwd"));
req.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(credentialBuffer));
req.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
return req;
} |
I have also noticed on occasion "The operation has timed out" error.
Not sure this is question for Apache forums as I dont see the error in Apache logs but since it says that remote host forcibly closed it, I thought it might be Apache or some Apache settings.
Please help,
Much appreciated, |

it KeepAlive enabled in Apache?
Does the client send a KeepAlive Signal?
Firefox for example requesting Apache Lounge
| Code: |
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding: gzip, deflate
Accept-Language: de,en-US;q=0.7,en;q=0.3
Cache-Control: max-age=0
Connection: keep-alive
Host: www.apachelounge.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0

Is KeepAlive enabled on Apache?
Yes, KeepAlive is ON, here is what I have in httpd.conf:
| Code: | KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 60 |
and what I have in httpd-mpm.conf:
| Code: | <IfModule mpm_winnt_module>
ThreadsPerChild 1000
MaxRequestsPerChild 0
Win32DisableAcceptEx
</IfModule> |
Does the client sends an KeepAlive signal?
It should, as KeepAlive is by default True and I haven't changed it in my override GetWebRequest() above. I also checked and it is set to True on my request.
Here is how my request and response look like, note that .NET AutomaticDecompression property sets/gets encoding for you, so there is no need to set Accept-Encoding but I did try setting it explicityly in my GetWebRequest() method by adding
| Code: | | req.Headers.Add("Accept-Encoding", "gzip, deflate"); |
Here is my request and response:
