Hi! You said your image was generated dynamically so I just assumed you used a servlet or a jsp for that generation. My misstake, I didn't mean to confuse you.
Anyway, your problem will be solved if you use the "random string" approach: <img src="\stat_image\stat.png;<%=System.currentTimeMillis()%>"> Solution 2: Create a filter to send no-cache headers and map it to *.png.
