# In HAProxy 1.5, we have to jump through some hops to accomplish a rewrite of a request's path...
# We use a temporary header to build our new path from the existing one in the request
# and then directly perform a redirect

# Clean the request and remove any existing header named X-Rewrite
http-request del-header X-REWRITE

# Copy the full request URL into X-Rewrite unchanged
http-request add-header X-REWRITE %[url] if { path_beg /foo }
