问个正则

HTML code

<%dim strstr = "Cache-Control: no-store, no-cache, must-revalidate,post-check=0, pre-check=0,privatePragma: no-cacheContent-Length: 32609Content-Type: text/htmlExpires: Sat, 18 Jan 1997 18:36:16 GMTSet-Cookie: bhCookieSaveSess=1; path=/Set-Cookie: bhCookieSess=1; path=/X-XSS-Protection: 0Date: Sun, 15 Apr 2012 12:54:21 GMTSet-Cookie: TSac8f66=cf69bf0e0f7faebafba0edada47b6bd4b0e5d8818c9eed6f4f8ac4fd; Path=/"' str 是一个http响应头，内含有很多回车%>

我怎么写正则，最后得到的结果是

result = "hCookieSaveSess=1; bhCookieSess=1; TSac8f66=cf69bf0e0f7faebafba0edada47b6bd4b0e5d8818c9eed6f4f8ac4fd; Path=/"

即，把所有的 Set-Cookie 的值合并，并丢弃重复的部分

[解决办法]
用正则
(?<=Set-Cookie: ).*?;//得到hCookieSaveSess=1;bhCookieSess=1; TSac8f66=cf69bf0e0f7faebafba0edada47b6bd4b0e5d8818c9eed6f4f8ac4fd;
在拼接就是了
[解决办法]
var reg=/Set-Cookie:.*/gi;
ps:
js正则不支持 (?<=)

换个问法吧，把除了Set-Cookie: ....; path=/以外的其他行都删除，正则怎么写？

str.replace(这里的正则怎么写？,'')

这可不可以理解成 除了提取 Set-Cookie: ....; path=/以外
其他什么都不提取？
