In order to read the content at a URL you can use URLREAD/URLWRITE Matlab commands. These functions allow user to use POST/GET methods. To achieve a deeper interaction with web server in some circustances you have to pass/read also the content of header. The header contains several notable items which include the value of the content-length header field, the value of the content-type header field, the content encoding of the resource that the URL references (or null if not known), the value of the expires header field, the sending date of the resource that the URL references, the value of the last-modified header field and many other useful parameters. For this reason we have developed two simple functions, based on original URLREAD and URLWRITE commands, that allow user to:
- read the header fields
- send proper header field to remote server
- set a timeout value
- save contents of URL to file
