winint timeout

[Oded]

Hi,
I'm using wininet API to perform uploading of big files to a server (IIS),
including going through authentication. Everything works just fine, except
that i keep getting timeout (at least this is what i think) after abuout 3
minutes.
The setting in the IIS are ok - using web config:
<httpRuntime maxRequestLength="208400" executionTimeout="1500"/>
i also checked when i drop this number to for example 15 seconds the
connection is stoped after around 30 seconds (because of the authentication
phase, i see 2 calls coming out from the client, the first fails
authentication and the seconds succeeds).
i tried setting the timeout using all possible flags i could find:
DWORD dwLength = sizeof(DWORD);
DWORD dwTimeut = 1500000; // 1500 seconds
InternetSetOption(hSession, INTERNET_OPTION_SEND_TIMEOUT, &dwTimeut,
sizeof(DWORD));
InternetSetOption(hSession, INTERNET_OPTION_DATA_SEND_TIMEOUT, &dwTimeut,
sizeof(DWORD));
InternetSetOption(hSession, INTERNET_OPTION_RECEIVE_TIMEOUT, &dwTimeut,
sizeof(DWORD));
InternetSetOption(hSession, INTERNET_OPTION_DATA_RECEIVE_TIMEOUT, &dwTimeut,
sizeof(DWORD));
InternetSetOption(hSession, INTERNET_OPTION_CONTROL_RECEIVE_TIMEOUT,
&dwTimeut, sizeof(DWORD));
InternetSetOption(hSession, INTERNET_OPTION_CONTROL_SEND_TIMEOUT, &dwTimeut,
sizeof(DWORD));

but i keep getting this timeout everytime without any change (it also
doesn't work when i set it to a smaller number e.g. 5 seconds).
i saw a few references about this feature not working properly, but i also
saw some people referring to it as working.
I have IE7 installed on my XP machine.
i would be very appriative if anyone can "shed some light" on this issue.
10x.

Hello,

What is the size of files? IIRC, internally wininet uses DWORD value to hold
the file size, os its limited only to 4 gb.

Hi,
Files are not reaching such sizes. Only a few 10s or 100s MB.
Anyway, i managed to solve it afterall. apperently beside the configuration
per application (in the web.config file), i had to change the default IIS
value on the whole website to higher value (default is 900 seconds...). Just
went to Properties->Website->Conenction timeout and updated the value.

What is strange is that i was under the impression that the web.config
values should have overwritten this value (since now all the applications
under this website have to have this long timeout).
