3799864 - ~path_info returns leading slash and preserves URL casing after upgrade to Release 2608 (IF_HTTP_SERVICE_EXTENSION)

The pseudo-header field ~path_info returned by the following call in custom ICF handler implementations behaves differently than in previous releases:

l_path = server->request->get_header_field( i_name = '~path_info' ).

The following behavior changes are observed:

• Prior to Release 2608: ~path_info was returned without a leading slash (/) and the value was converted to lower case
• After Release 2608: ~path_info is returned with a leading slash (/) and the original URL casing is preserved

Custom HTTP service implementations that perform path-based routing, URL validation, or string comparisons against hardcoded path values may fail silently or reject requests that were processed successfully before the upgrade.
