Class Description

                                                                      
 TWebFile                                                             
                                                                      
 A TWebFile is like a normal TFile except that it reads its data      
 via a (slightly modified) apache web server. A TWebFile is a         
 read-only file.                                                      
                                                                      

 Create a Web file object. A web file is the same as a read-only
 TFile except that it is being read via a HTTP server. The url
 argument must be of the form: http://host.dom.ain/file.root.
 If the file specified in the URL does not exist or is not accessible
 the kZombie bit will be set in the TWebFile object. Use IsZombie()
 to see if the file is accessible. The preferred interface to this
 constructor is via TFile::Open().

 Create a Web file object. A web file is the same as a read-only
 TFile except that it is being read via a HTTP server. Make sure url
 is a valid TUrl object.
 If the file specified in the URL does not exist or is not accessible
 the kZombie bit will be set in the TWebFile object. Use IsZombie()
 to see if the file is accessible.

 Initialize a TWebFile object.

 A TWebFile that has been correctly constructed is always considered open.

 Reopen a file with a different access mode, like from READ to
 UPDATE or from NEW, CREATE, RECREATE, UPDATE to READ. Thus the
 mode argument can be either "READ" or "UPDATE". The method returns
 0 in case the mode was successfully modified, 1 in case the mode
 did not change (was already as requested or wrong input arguments)
 and -1 in case of failure, in which case the file cannot be used
 anymore. A TWebFile cannot be reopened in update mode.

 Read specified byte range from remote file via HTTP daemon. This
 routine connects to the remote host, sends the request and returns
 the buffer. Returns kTRUE in case of error.

 Set position from where to start reading.

 Return maximum file size to by-pass truncation checking.
