remap plugin won't work
### Brief
calling the following functions before **TS_HTTP_POST_REMAP_HOOK** cause
rule in remap plugin don't work.
```c++
TSUrlPortSet();
TSUlPathSet();
TSUrlHostSet();
TSUrlSchemeSet();
```
here is one line in `remap.config`
```
map http://192.168.16.174/ http://192.168.16.174/ @plugin=libtslua.so
@pparam=/usr/local/etc/trafficserver/sta_modifyurl.lua
```
-----
### Detail
here is code fragment from `cacheurl.cc`, the left side only `#if 1` and
`#endif` is new code and the right side is a new header file to modify client
request url.
the hook point is **TS_HTTP_READ_REQUEST_HDR_HOOK**
the code in above picture will cause the `libtslua.so` won't work, even not
enter in any of the following functions in `ts_lua.c` (the ts-lua plugin source
is [here](https://github.com/portl4t/ts-lua))
```c++
TSReturnCode
TSRemapInit(TSRemapInterface *api_info, char *errbuf, int errbuf_size);
TSReturnCode
TSRemapNewInstance(int argc, char *argv[], void **ih, char *errbuf, int
errbuf_size);
void
TSRemapDeleteInstance(void *ih);
TSRemapStatus
TSRemapDoRemap(void *ih, TSHttpTxn rh, TSRemapRequestInfo *rri);
static int
globalHookHandler(TSCont contp, TSEvent event ATS_UNUSED, void *edata);
```
-----
So, what's wrong after calling those **Set** functions, and how to solve
this problem ?
Thank you!
