Probably more of a ruby question than a rails question but I am trying  
to retrieve a file from my web server that requires ssl but uses a self  
signed certificate.

Looking through all of the documentation at  
[http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/index.html](http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/index.html)  
and  
[http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/classes/Net/HTTP.html](http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/classes/Net/HTTP.html)

I don’t see any way that I could do something equivalent to like wget…

wget -no-check-certificate [https://myserver/myfile.txt](https://myserver/myfile.txt)

Is there any way to accomplish this with net/http or do I have to  
execute a shell wget and open the file locally?

Craig

OK, I think I have this solved but I’m hamstrung by a ‘?’ in the URL…

in console…

and if I substitute %3F for the ? it will accept the ‘path’…

but it doesn’t work

nor does this URL work with wget…

wget --no-check-certificate  
[https://craig](https://craig):\*\*\*\*\*@my\_server//horde/kronolith/ics.php%  
3Fc=5be410ec5238fc93c1f66b1a935365c9

=\> `ics.php?c=5be410ec5238fc93c1f66b1a935365c9.1’

of course with a ? instead of %3F, it works

How does one use net/http (net/https) with URL’s that have a ?

?
