I'm trying to remove Proxy-Authorization dedicated to local subscriber without -and not the other ones dedicated to other server- I realized that "consume_credentials" doesn't work because it requires that a call to "www_authorize, proxy_authorize, www_authenticate or proxy_authenticate" has been made before. I have a use-case where this isn't called. I don't want to use such code: if (is_present_hf("Proxy-Authorization")) { remove_hf("Proxy-Authorization"); } Because this may remove a "Proxy-Authorization" for another service. I have seen this: has_credentials but it doesn't help to know which header is the one containing the header... Any good way to find the header and index? And then remove it with remove _hf_value2? I haven't looked for the options offered by the textopsx module, being added by ser devs in the past, but if your case of not doing www/proxy_authenticate() or auth_check() is to avoid a database query, then do pv_auth_check(...) with a random password and the proper relam. Ignore the result, the header is parsed, even if authentication fails, and you should be able to use consume_credentials().
