url size problem

[Songqing Chen]

hi, guys,

since I need to re-write the url inside with some suffix, so in function
parseHttpRequest(...) 

        /* URL may be rewritten later, so make extra room */
        url_sz = strlen(url) + Config.appendDomainLen + 5;
        http->uri = xcalloc(url_sz, 1);
        strcpy(http->uri, url);

I add an additional 10.

However, sometimes the system can catch Segment Fault, for invaild memory 
refernce when it tries to free(http->uri).

I guess the problem is from this, but not sure. Anyone has any idea on 
this?

thanks in advance.
