Re: remap rules based on request header
After adding lua plugin with remap rule in remap.config and writing some
sample code mentioned in
https://docs.trafficserver.apache.org/en/latest/admin-guide/plugins/ts_lua.en.html#ts-client-request-set-url-host
I see the following error in traffic server.
[May 8 08:57:44.851] Server {0x2aeb0862c2c0} WARNING: Failed to create new

Is there any thing that I am missing out?
Thanks

remove this 'param'

Re: remap rules based on request header
Posted by Shu Kit Chan <ch...@gmail.com>.
Worked with Adi offline.
Basically we just need to specify the exact location of the lua
script. And it loaded now.
Thanks.

1) Which ats version you are using? - 5.3.x
2) How do you compile/get libtslua.so ? - internal build from experimental

3) anything in error.log ? - nothing other than the one posted

A few questions
1) Which ats version you are using?
2) How do you compile/get libtslua.so ?
3) anything in error.log ?

Re: remap rules based on request header
Posted by Adi Mallikarjuna Reddy V <ad...@gmail.com>.
its libtslua.so, we built it as this.
didnt work after removing @pristine_host_hdr=1 and enabling the same
through lua script.
I see the same error after above change. Looks like something to do with
initialization of plugin.
Thanks
Adi

RE: remap rules based on request header
Posted by "Chou, Peter" <pb...@labs.att.com>.
Can you confirm under $PREFIX/libexec whether your so is libtslua.so or just tslua.so?

No extra info with debug tag ts_lua enabled, as this seems to be failing to parse the remap config itself.

Re: remap rules based on request header
Posted by Adi Mallikarjuna Reddy V <ad...@gmail.com>.
remap rule
map /random_path http://dummy_destination.com/ @pristine_host_hdr=1
@plugin=libtslua.so @pparam=lua_remap.lua
script - lua_remap.lua
function do_remap()
ts.client_request.set_url_host('actual_destination.com')
ts.client_request.set_url_port(80)
ts.client_request.set_url_scheme('http')
return TS_LUA_REMAP_DID_REMAP
end
No extra info with debug tag ts_lua enabled, as this seems to be failing to
parse the remap config itself.
Thanks
Adi

Re: remap rules based on request header
Posted by Jeremy Payne <jp...@gmail.com>.
verify your remap rules and/or lua scripts to ensure they are syntactically
correct.
also enable debug.. .may provide further insight..
can you also share your remap file and corresponding lua scripts ?
