Be careful is executing pdm_webcache -b as this can annoy your users. When using the -b argument, the users will be prompted to clear their browser cache every time they access Service Desk for a 24 hour period. This can be very useful for changes to items that get cached on the client-side, such as javascripts. However, it can be very annoying to users to frequently access Service Desk. In addition, after the 24 hours no additional messages will be generated so users who did not login during this window will not get the prompt. While the concept of the -b argument is good, it's usually not a practical option.
