◆ TUrl() [2/3]

TUrl::TUrl ( const char *  url,
Bool_t  defaultIsFile = kFALSE 
)

Parse url character string and split in its different subcomponents.

Use IsValid() to check if URL is legal.

url: [proto://][user[:passwd]@]host[:port]/file.ext[?options][#anchor]

Known protocols: http, root, proof, ftp, news and any special protocols defined in the rootrc Url.Special key. The default protocol is "http", unless defaultIsFile is true in which case the url is assumed to be of type "file". If a passwd contains a @ it must be escaped by a \, e.g. "pip@" becomes "pip\\@".

Default ports: http=80, root=1094, proof=1093, ftp=20, news=119. Port #1093 has been assigned by IANA (www.iana.org) to proofd. Port #1094 has been assigned by IANA (www.iana.org) to rootd.
