problem with saving data on web server through arduino ethenet shield

Using Arduino Networking, Protocols, and Devices
1

Dear Sir
I want to save data gathered from analog sensors on a web server and I use an arduino uno and an ethernet shield to do that..
It should save data every 10 second..
but it saves data just 3 or 4 times a day..
I contact my webserver technical support, There is no any policy from their side and I do not know what is wrong with my board and what is the problem..
please help me with that.. :confused: :confused: :frowning: :frowning:

Regards
Narges

do you have a small delay before closing the client after sending the request?
