portl4t commented on TS-2930:
-----------------------------
I think we should retrieve the client_request's url with
TSHttpTxnEffectiveUrlStringGet(...) before PRE_REMAP. By the way, I can get the
whole url from POST_REMAP.
> Missing hostname in ts.client_request.get_url()
> -----------------------------------------------
>
> Key: TS-2930
> URL: https://issues.apache.org/jira/browse/TS-2930
> Project: Traffic Server
> Issue Type: Bug
> Components: Lua, Plugins, TS API
> Affects Versions: 5.0.0
> Reporter: Nikolai Gorchilov
> Assignee: Kit Chan
>
> In Linux TPROXY forwarding mode ts.client_request.get_uri() omits hostname
> from the returned url - responds with "http:///pathname?parameters"; instead
> of "http://hostname/pathname?parameters";. This happens in the context of
> early state hooks up to and including TS_HTTP_POST_REMAP_HOOK.
> In case of cacheurl.so rewrite on the URL, hostname reamains empty even after
> post_remap.
> Here're the steps to reproduce the problem - a global lua plugin
> (plugins.config):
> ==========[cut]==========
> function do_global_txn_start()
> print('==========[cut]==========')
> print ('do_global_txt_start: ' .. ts.client_request.get_url())
> end
> function do_global_txn_close()
> print ('do_global_txn_close: ' .. ts.client_request.get_url())
> print('==========[cut]==========')
> end
> function do_global_os_dns()
> print ('do_global_os_dns: ' .. ts.client_request.get_url())
> end
> function do_global_pre_remap()
> print ('do_global_pre_remap: ' .. ts.client_request.get_url())
> end
> function do_global_post_remap()
> print ('do_global_post_remap: ' .. ts.client_request.get_url())
> end
> function do_global_read_request()
> print ('do_global_read_request: ' .. ts.client_request.get_url())
> end
> function do_global_send_request()
> print ('do_global_send_request: ' .. ts.client_request.get_url())
> end
> function do_global_read_response()
> print ('do_global_read_response: ' .. ts.client_request.get_url())
> end
> function do_global_send_response()
> print ('do_global_send_response: ' .. ts.client_request.get_url())
> end
> function do_global_cache_lookup_complete()
> print ('do_global_cache_lookup_complete: ' ..
> ts.client_request.get_url())
> end
> function do_global_read_cache()
> print ('do_global_read_cache: ' .. ts.client_request.get_url())
> end
