After several tests, I found that OpenLayers sends request for 2 tiles with
different longlat with the same Row and col. 
example
http://172.31.101.109:8080/servlet/getImageWWJ1?x1=51.375&y=25.96875&x=51.46875&y1=26.0625&level=4&row=618&col=1234

http://172.31.101.109:8080/servlet/getImageWWJ1?x1=51.46875&y=25.96875&x=51.5625&y1=26.0625&level=4&row=618&col=1234

these tow requests are for tow different tiles, as you can see the bounds
for the tiles are different, but the column, row and Zoom level are the
same, which return the same image for different tiles.

After requsting the tiles from on fly process (not cached tiles) which
create the image based on bounds, every things worked fine.
