I second that - that's, for instance, how Google's auto-completion (of addresses in gmail, search terms in search etc) works - it sets a background JavaScript thread which runs every second in the background, reads the input field's value and submit it to the server for process if it changed (and pulls the results, of course). You can skip the "check input field value" part in your case. There must be some JavaScript libraries which can already help you there (http://jquery.com/ is the first suspect, but there must be many more lying around). Two less related points: 1. Make sure you verify the URL for any hockery-pockery (e.g. that it's a genuine legitimate "http(s)://" URL and not, for instance "file:///etc/passwd" or trying to break out of the shell parameter quoting to inject its own shell commands or encoded javascript that can be used for cross-site-scripting :) 2. While I'm looking for work, I might be available for such small jobs (I'm not a JavaScript Guru, more of a server-side guy, but should be able to do something like this with some research). --Amos > > David > > -- > בברכה, > דוד רונקין > נא בקרו בבלוג שלי: http://dronkin.blogspot.com > > > 2011/12/13 Hetz Ben Hamo <het...@gmail.com> > >> Hi, >> >> I've written a simple bash script to upload a file from a remote server >> as a CGI script (yes, I know, I should use another language, but it's just >> a proof-of-concept). >> >> It goes like this: A simple HTML page gives the user a text line to enter >> a URL and "upload" button, which submits the data using POST to a bash >> script (I use the proccgi for transferring the values). >> >> The scripts fetches the URL and launches wget to grab the file, rename it >> and move it to a specific directory. >> >> So far, so good.
