Hi Alex, as far as i know, steelapp needs a virtualserver for each port. But you can put all nodes into a single-pool and then use trafficscript to decide which node to use request.getLocalPort() gives you the localport pool.select( "mypool", "mynode", myport ); let you choose which node should be used with pool.listfailednodes( Pool ) you see which nodes are failed at the moment (so choose another one from pool.listactivenode(Pool) ) and finally request.getRemoteIP() gives you the ip of the client This is fine, as long as you have only one node to response to a request, But if you want "real" load-balancing (let steelapp decide which node to use), then you have to group nodes together (and so create different pools), thats easier are "trafficscript-based-load-balancing". btw, which application are you using that require such a load-balancing-scheme? -Jochen ...

i've tried to make a similar request on our site, without success. pls post your curl-test, my test was: curl -H "Content-Length: 100" -H "Content-Length: 200" http:/myserver and it ended in a "bad request" ... View more

we did have a similiar problem, because the server is sending a different answer depending on user-agent value. so testing with a real browser is different. could you do a "curl" to that url and see whats coming back? ... View more

Hi Mike, as far as i understand the concept, the optimizer is part of the "steelapp adc", which means, it runs "in front" of your existing web-server, doesn't make a difference if it is apache or iis (it runs standalone). -Jochen ... View more

we do have some similar problem, so what we do is just trafficscript, no particular error-files, but a html-response via http.sendresponse so, either check a whole pool via if pool.activenodes("<yourpoolname>") == 0 {      # send back an error via http.sendresponse(....) } or check a single node via pool.checknode("<yourpool>","<yournodename>","<yourport>"); ...

Hi Munim, depending on the information you get with your first request (http-headers, expires setting, cache-control etc.) you can make the decision if you have to request it again... -Jochen ... View more

Hi, you can request the external file via $body = http.request.get( "https://www.example.com/",   "Cookie: foo=bar" ); then store the result (json) in memory (after your modification) via data.set("mycache",$body); and deliver the result, depending on cache setting (how do you know that the external content had changed without requesting it every time?) you can fetch your stored value via $body = data.get("mycache"); deliver the result with http.sendResponse( "200 OK",                  "application/json",                  $body,                  "" ); -Jochen ...

your problem is the mimetype, your image will be send as "text/html", which is wrong. copied from somewhere here: if (resource.exists($filename)) {          $mimes = [          "html"   => "text/html",          "jpg"    => "image/jpeg",          "jpeg"   => "image/jpeg",          "png"    => "image/png",          "gif"    => "image/gif",          "js"     => "application/x-javascript",          "css"    => "text/css"  ,          "ico"    => "image/x-icon" ,          "txt"    => "text/plain"          ];          if( string.regexmatch( $filename, ".*\\.([^.]+)$" ) ) {             $mime = $mimes[ $1 ];          }          if( ! $mime ) $mime = "text/plain";          #          # Serve the file from the conf/extra directory          $contents = resource.get( $filename );          $header = "Content-Length: ".string.len($contents)."\r\n".                    "Expires: ".sys.gmtime.format( "%a, %d %b %Y %T GMT", sys.time()+604800 )."\r\n".                    "Cache-Control: max-age=604800\r\n".                    "";           http.sendResponse( "200 OK", $mime, $contents, $header );          #       } Best Regards, Jochen ...

we are using a http-healthcheck (Pools - Health Monitoring), e.g. check your  nodes via   "/checkdb.php" (depending on your environment php maybe not suitable). this php-script checks DB Connectivity, and returns OK/NOK (we are not using php, so i can't provide a example, our healthcheck is part of our own application) within the health-monitor, just define the "body_regex:" as "OK". If you have setup this, STM will check your nodes every few seconds if this URL still returns OK, if not, the node will be marked as failed. then, within a rule (assigned to your vserver), you can check, if nodes for your pool are available if (pool.activenodes("yourpoolname") < 1 { http.sendresponse(....your maintenance message); } if you want to use zcli, there is full documentation with functions... ... View more

you are able to disable a rule from external e.g. through zcli program. but nevertheless, imho the best way to achieve what you want would be a health-check within a pool. Health Checks are done via nodes (which is normally not your DB Server), so what we've done is creating a small page within our app-server (=node), this page just checks if DB is running, and returns OK/NOK. And we implemented a custom-healthcheck, calling this page via http request, and checking if return body is OK. If there is a DB-Problem, all nodes will be disabled automatically, and you can do something different through trafficscript "pool.activenodes" function (e.g. showing maintenance via .http.sendresponse) ...

create a vserver for something.domain.com then use a rule to 1. set the http header to the correct value (i guess http.setHeader( "Host", "something.domain.com" ); 2. set the url http.setPath( "/something" ); 3. create a pool (named "poolwithoneserver") with one server: server.domain.com:80 4. last statement of the rule: pool.use("poolwithoneserver"); so, your existing server is just a node for a different vserver, and you have to modify the path and the hostheader for every request. ...

Hi Aaron, a http.redirect immediately sends out the response and further traffic script will not be executed. Thats why your rule just ends at the line "http.redirect". But what do you want to achieve? a redirect tells the browser "got to the new url", so your old url will not be displayed/used anymore. If you want to keep the old URL in the browser and just show content from the new, you can use the new one as a "node" (but linking withing the website could be tricky...) -Jochen ... View more

Hi David, i don't have any experience with F5 Config Files, as we switched from another solution to STM. We used a small script creating zcli commands to create ~200 trafficips, vservers, corresponding pools, settings etc. did take some hours to create the script and then just minutes and the config is finished... just as a hint how to create a vserver via zcli (command line tool), as we have two datacentres with more or less the same configuration a little bit more than you need: TrafficIPGroups.addTrafficIPGroup www.example.com_DC1,{ ipaddresses: [192.168.1.10], machines: [STM1.DC1.tpi,STM2.DC1.tpi] } TrafficIPGroups.addTrafficIPGroup www.example.com_DC2,{ ipaddresses: [192.168.1.10], machines: [STM1.DC2.tpi,STM2.DC2.tpi] } VirtualServer.addVirtualServer ex_i66_www.example.com_HTTP,{ default_pool: ex_i66_ui_v6, port: 80, protocol: http } VirtualServer.addVirtualServer ex_i66_www.example.com_HTTPS,{ default_pool: ex_i66_ui_v6, port: 443, protocol: http } VirtualServer.setListenTrafficIPGroupsByLocation DC1,[ex_i66_www.example.com_HTTP],[[www.example.com_DC1]] VirtualServer.setListenTrafficIPGroupsByLocation DC2,[ex_i66_www.example.com_HTTP],[[www.example.com_DC2]] VirtualServer.setListenTrafficIPGroupsByLocation DC1,[ex_i66_www.example.com_HTTPS],[[www.example.com_DC1]] VirtualServer.setListenTrafficIPGroupsByLocation DC2,[ex_i66_www.example.com_HTTPS],[[www.example.com_DC2]] TrafficIPGroups.setEnabled www.example.com_DC1 enabled TrafficIPGroups.setEnabled www.example.com_DC2 enabled VirtualServer.setEnabled ex_i66_www.example.com_HTTP true VirtualServer.setEnabled ex_i66_www.example.com_HTTPS true VirtualServer.setCompressionEnabled ex_i66_www.example.com_HTTP true VirtualServer.setCompressionEnabled ex_i66_www.example.com_HTTPS true VirtualServer.setWebcacheEnabled ex_i66_www.example.com_HTTP true VirtualServer.setWebcacheEnabled ex_i66_www.example.com_HTTPS true VirtualServer.setRequestTracingEnabled ex_i66_www.example.com_HTTP true VirtualServer.setRequestTracingEnabled ex_i66_www.example.com_HTTPS true VirtualServer.setLogEnabled ex_i66_www.example.com_HTTP true VirtualServer.setLogEnabled ex_i66_www.example.com_HTTPS true VirtualServer.setProtection ex_i66_www.example.com_HTTP ex_service_protection VirtualServer.setProtection ex_i66_www.example.com_HTTPS ex_service_protection VirtualServer.setResponseRules ex_i66_www.example.com_HTTP,{ enabled: true, name: ex_response, run_frequency: run_every} VirtualServer.setResponseRules ex_i66_www.example.com_HTTPS,{ enabled: true, name: ex_response, run_frequency: run_every} VirtualServer.setRules ex_i66_www.example.com_HTTP, [{ enabled: true, name: ex_httpsrewrite, run_frequency: run_every}{ enabled: true, name: ex_i66_poolchoose, run_frequency: run_every}{ enabled: true, name: ex_nohomepageredirecttologin, run_frequency: run_every}] VirtualServer.setRules ex_i66_www.example.com_HTTPS, [{ enabled: true, name: ex_request, run_frequency: run_every}{ enabled: true, name: ex_i66_poolchoose, run_frequency: run_every}] VirtualServer.setTimeout ex_i66_www.example.com_HTTP 300 VirtualServer.setTimeout ex_i66_www.example.com_HTTPS 300 VirtualServer.setAddXForwardedForHeader ex_i66_www.example.com_HTTP true VirtualServer.setAddXForwardedForHeader ex_i66_www.example.com_HTTPS true VirtualServer.setSSLCertificate ex_i66_www.example.com_HTTPS www.example.com VirtualServer.setSSLDecrypt ex_i66_www.example.com_HTTPS true just copy/paste to zcli ...

you want to send a 410 to the client for every request right? so a trafficscript line of http.sendResponse( "410 Gone", "text/html", "Gone", ""); should do the job.

1. pool.use: When used in a request rule, aborts all rules processing and specify the pool to give the request to. that means your trafficscript ends on the line pool.use( "Example" ); 2. you are only checking one node, i would do it different: if ((pool.activenodes("Example") > 1)) { # you have at least 2 working nodes    pool.use("Example"); # your script will end here in normal operation } # you only come to this line, if you have no working node in pool "Example" http.changeSite("http://www2.example.com"); # as an alternative, you can do a redirect, depending on your requirements: # http.redirect( "http://www2.example.com/" ); ...
