<LI>If you want the timeout value to be "forever" then you can specify a
|
|
|
32 |
|
|
|
33 |
the image you will have to remove the image files from the cache. This
|
|
|
34 |
removal could for example be handled by a nightly cron-job</LI>
|
|
|
35 |
<LI> If you use images where you have enabled the anti-aliasing you
|
|
|
36 |
should strongly consider using caching since anti-aliasing is quite
|
|
|
37 |
time consuming compared to standard line drawings.</LI>
