Is there a TCL equivalent for php's readfile function?

Question

The Situation:
Imagine two servers A and B. Server B just outputs a PDF file that nicely displays information retrieved from any xml string passed to it via a url parameter. Server A's job is to build an xml string, append this xml string onto a url (pointing to the code on Server B) as a parameter, and then call the url using php's readfile() function...

The Question:
Is there a way to do the same thing (readfile on remote server and output to browser) in TCL?

Answer 1

The TCL readfile equivalent is file http://www.tcl.tk/man/tcl8.6/TclCmd/file.htm

However, it appears that the PHP readfile function has an option to read a file from a URL if the fopen wrappers have been enabled http://php.net/manual/en/function.readfile.php

So in this case you need to use a HTTP client. Try this http://www.tcl.tk/man/tcl8.6/TclCmd/http.htm and there is an example of how to use it here http://wiki.tcl.tk/24061
