Hello all,

```
      I need few suggestions on how to pass the parameters to a URL

```

through curl. Currently I can do that using system() and %x[] through  
which I could give the curl command. But since these two executes the  
curl as a shell command I don’t want to use these to do that. For  
example I’m using it in this way in the controller code.

system(“curl -I -H &parameter=‘#{}’ [http://x.x.x.x/yyy/zzz.ext](http://x.x.x.x/yyy/zzz.ext)”)  
or  
%x[curl -I -H &parameter=‘#{}’ [http://x.x.x.x/yyy/zzz.ext](http://x.x.x.x/yyy/zzz.ext) ]

Is there any plug-ins or gems in rails which I can use to send the  
parameters using the curl and not executed as a shell command? If any  
please suggest. Now I’m using system() or %x[] which I want to evaluate  
because it executes the content in that as a shell command.

Thanks in advance and Regards.

Search for ruby + libcurl for other suggestions, but patron might do  
what you want.
