> I'm trying to write a plugin to change CacheUrl for some reason.
> It works fine if I only call TSCacheUrlSet().
> However, if TSHttpTxnCacheLookupUrlGet() was called after TSCacheUrlSet(), EffectiveUrl will be changed to the new CacheUrl.
> Scenario without calling TSHttpTxnCacheLookupUrlGet:
>    Origin Request URL: http://www.example.com/a
>    CacheUrl: http://www.example.com/abc
>    Expect Request URL: [Same as Origin Request URL]
>    Effective URL: [Same as Origin Request URL]
> Scenario with calling TSHttpTxnCacheLookupUrlGet:
>    Origin Request URL: http://www.example.com/a
>    CacheUrl: http://www.example.com/abc
>    (Calling TSHttpTxnCacheLookupUrlGet() here)
>    Expect Request URL: [Same as Origin Request URL]
>    Effective URL: http://www.example.com/abc
