We need to bulk publish content (10000s of pages). They are created as a scheduled event so require almost immediate publish for all the pages in one go. Main challenge is how to invalidate content on dispatcher (10000s of pages) and then re-fetch these pages again (on multiple dispatchers).
What is the best strategy to do this ?? Is there a possibility of leveraging network storage for dispatcher cache??
You can issue an HTTP request that causes the dispatcher to delete cached files, and immediately retrieve and recache the file.
Delete and immediately re-cache files when web sites are likely to receive simultaneous client requests for the same page. Immediate recaching ensures that Dispatcher retrieves and caches the page only once, instead of once for each of the simultaneous client requests.
Also, you can write a flush-cache servlet which can send an invalidate request to Dispatcher and can recache the content. Please take necessary precautions while implementing the flush-cache servlet. Please see the link below for more details:
