Actually, this one works for me quite well - it should work fine for
following scenarios:

.../186
.../186/
.../186/index.html

In any other case, it will fail, as you can see:

$ perl -e 'print "YES" if "webcast_data/186" =~
m|^webcast_data/(\d+)/?(index\.html)?$|;'
YES

$ perl -e 'print "YES" if "webcast_data/186/" =~
m|^webcast_data/(\d+)/?(index\.html)?$|;'
YES

$ perl -e 'print "YES" if "webcast_data/186/index.html" =~
m|^webcast_data/(\d+)/?(index\.html)?$|;'
YES

$ perl -e 'print "YES" if "webcast_data/186/asdf.html" =~
m|^webcast_data/(\d+)/?(index\.html)?$|;'
