How do I include all incoming URL parameters (i.e. list_content.rhtml?content_id=23) in my link_to statements? I know I can include specific parameters in the link_to, by using ":variable_name => 123" in the link_to statement... But what If I dont' know what the incoming parameters will be... and I simply want to include them along with any other specific variables I choose. I am using sortable columns in a table, and need to reload the page -- and I'm trying to use some common functions for this.. .but I'm getting hung up with knowing what the incoming params are and including them on all my links.

Your logic in the controller's action (eg 'list_content') should handle the different combinations of parameter values. Lindsay
