playframework - What happens if WSRequest has too many get() parameters? -

-

i have rather bizarre question , not find answer anywhere. building wsrequest request in play! 2.4.3 , adding query params using setqueryparameter() request. after that, send them server using request.get() , retrieving result.

everything works fine, curious, happen if parameters exceed limit of get(). need check , make 2 individual requests? handled somewhere or return exception?

thanks

i did not see numbers in documentation, know - there no limit query string in standards, it's depend realisation. what maximum possible length of query string?. pretty sure server can stuck in problem long query string before server.

my proposed solution check simple code:

package controllers;  import javax.inject.inject;  import play.*; import play.mvc.*;  import play.libs.ws.*; import play.libs.f.promise;  public class application extends controller {      @inject wsclient ws;      public promise<result> index() {         wsrequest request = ws.url("http://httpbin.org/get");         int paramsnumber = 100;         for(int i=0; i<paramsnumber; i++){           request.setqueryparameter("paramkey" + i, "paramvalue" + i);         }         return request.get().map(response -> ok(response.getbody()));     }  }

so, "http://httpbin.org/get" takes 100 params (and play can create , send of course). , 1000 params returns "414 request-uri large" play still able create , send 1000 params without error.

i pretty sure question not in max param numbers in max query string length.

update

i run netcat echo locally - nc -l 8888 , did request url http://127.0.0.1:8888 100000 parmeters, &paramkey99999=paramvalue99999 - works charm. can answer: play 2.4.3 can send @ least 100000 params in the ws request totaly length of 2 600 000 chars. sure suppose have more parameters ?

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
