* CommitUrlCacheEntryInternal (Compensates for an MS bug)
*
* The bug we are compensating for is that some drongo at Microsoft
* used lpHeaderInfo to pass binary data to CommitUrlCacheEntryA.
* As a consequence, CommitUrlCacheEntryA has been effectively
* redefined as LPBYTE rather than LPCSTR. But CommitUrlCacheEntryW
* is still defined as LPCWSTR. The result (other than madness) is
* that we always need to store lpHeaderInfo in CP_ACP rather than
* in UTF16, and we need to avoid converting lpHeaderInfo in
* CommitUrlCacheEntryA to UTF16 and then back to CP_ACP, since the
* result will lose data for arbitrary binary data.
