2.why refreshing of cache in sxi_chache will resolve many errors in adapter engine etc etc, like the one issue resolved in the below forum?
3.In what all the specific situations we refresh cache in IR, ID and SXI_CAHCE?
Cache is nothing but a buffer kinda where all the recently accessed data r stored.
so sometimes even after making changes u access the page the old data/page is displayed...
so Web AS cache works as a normal refresh deleting all the recently accessed data/pages...
it clears or frees ur memory so tht no irrelevant data is obtained...
for further details, refer to google search... " Web AS Cache Refresh in SAP-Xi"
