Daniel, I have successfully implemented the router in lua using a lua script called from a "LuaHookFixups" directive. LuaHookFixups /var/www/lua/myscript.lua router -- /var/www/lua/myscript.lua function router(r) local route = get_route(r) if route then r.filename = "proxy:balanc

I'm interested in knowing how you did it in mod_python. Do you use an external http lib and process the result yourself? That's certainly also possible with mod_lua. With regards, Daniel. On 12/18/2015 05:12 PM, Daniel Gruno wrote: > I think you need two phases here, as mod_lua doesn't itself do

I think you need two phases here, as mod_lua doesn't itself do the proxying, but delegates it to mod_proxy. First, http://modlua.org/recipes/loadbalancing will show you how to proxy. Secondly, you could then set up a handler for the specific HTTP code using ErrorDocument or an output filter. I h

I'm not a mod_lua expert, esp as it relates to exposing the full Apache httpd API... it is possible that using r.handler and specifying the proxy may work. > On Dec 18, 2015, at 8:05 AM, Jose Thomas wrote: > > Jim, > > Sorry, I could not find the documentation on how to do this using mod_lua.

Jim, Sorry, I could not find the documentation on how to do this using mod_lua. Can you please point me there ? In my current setup which is on httpd 2.2 - we use modpython. For routing requests (based on a header) we use a simple python script. For refiring the request (when a custom response co

In general, if you prepend the URL w/ 'proxy:' and then use it in a subrequest, it will be processed as a proxy request. > On Dec 17, 2015, at 9:21 AM, Jose Thomas wrote: > > All, > > I am using httpd 2.4 with mod_proxy (http) routing requests to multiple > backends. > > I have a strange requ

2015-12-17 Thread Jose Thomas
All, I am using httpd 2.4 with mod_proxy (http) routing requests to multiple backends. I have a strange requirement. If a backend responds with a custom response code - i need to re-execute the request to a different backend. What would be the right way to implement this functionality ? I was l
