In Omeka exhibit mode, the URL of item is show in the format similar to /items/show/123, where 123 is the Omeka item id. for example.
As for my case, each item has its own id field, eg. record=B123456X.
How can I customize the URL of the items in exhibit, such that the URL shows "http://mysite.com/record/B123456X" instead of "http://mysite.com/items/show/123"? Any way to redirect or rewrite the URL to the format I want when displaying the item page?
