# TSHttpHdrCopy(3ts)

copies the contents of the HTTP header located at src\_loc within src\_bufp to the HTTP header located at dest\_loc within dest\_bufp

## NAME

TSHttpHdrCopy - copies the contents of the HTTP header located at src\_loc within src\_bufp to the HTTP header located at dest\_loc within dest\_bufp

## SYNOPSIS

```
#include <ts/ts.h>
```

- ***TSReturnCode* TSHttpHdrCopy(*TSMBuffer* dest\_bufp, *TSMLoc* dest\_offset, *TSMBuffer* src\_bufp, *TSMLoc* src\_offset)**

  ## DESCRIPTION

*TSHttpHdrCopy()* works correctly even if *src\_bufp* and *dest\_bufp* point to different *Marshal Buffers*. Make sure that you create the destination HTTP header before copying into it.

**NOTE:**

*TSHttpHdrCopy()* appends the port number to the domain of the URL portion of the header. For example, a copy of *http://www.example.com* appears as *http://www.example.com:80* in the destination buffer.
