I'm building a link that has an encrypted key that we generate and that key can include the underscore character.  I'm using the below link to post to some social sites and when the user clicks the link it strips off the "_".  Any ideas on how to escape this or how to build the link so that the "_" is included in the users request?

You can try replacing the underscore with the unicode equivalent (perhaps they don't check for this value).

Any of these should work:

maybe it's a facebook issue as other social sites handle it, but when I paste in http://linkcontextroot/EM6_;  the escape code doesn't get converted to the _.  I need the _ to be interpreted as a _.  I tried the Unicodes as well

Can you try to handle this instead on your server?  I.e., if facebook won't change &#95 or &#005F, can you decrypt those into ASCII before using that string as a key for your web application?
