URI Based Filtering using ASM Module ?

you can use the source IPs to differentiate what paths are accessible and can incorporate that directly into your policy, either by address list in the policies or via datagroups. Here's the address list version:

ltm policy access_by_src_ip {
    controls { forwarding }
