-------------------------------------

             Summary: Port number padded with 0 when Host header has explicit port specification
                 Key: TS-3222
                 URL: https://issues.apache.org/jira/browse/TS-3222
             Project: Traffic Server
          Issue Type: Bug
            Reporter: Nakagome Tomoyuki


Due to this line in proxy/hdrs/HTTP.cc:1552

{noformat}
ui->m_len_port = sprintf(port_buff, "%.5d", hdr->m_port);
{noformat}

UrlPrintHack::UrlPrintHack() prepends unnecessary '0's so the port_buff will be 5 chars, like "00080". Suggestion is to remove .5 from the format string and change it to

{noformat}
ui->m_len_port = snprintf(port_buff, 6, "%d", hdr->m_port);
{noformat}

unless there are some specific reasons for the current code.

To replicate the symptom, send a request with a Host header having a port number like:

Host: www.apache.org:80
