i trying write rewrite rule return 404 on urls spam parameters. used following rewrite tool return error 404 query string voxter.pdf&gpvoq , parameters gpvoq not producing 404 error. rewritecond %{voxter.pdf&gpvoq} (^|&)parm1=gpvoq [nc] rewriterule (.*)/error-404.php? [r=404,l] can u please me mistake doing? %{voxter.pdf&gpvoq} isn't apache variable. match literal. need using %{query_string} variable instead: rewritecond %{query_string} (voxter.pdf|gpvoq) [nc] rewriterule ^ /error-404.php? [r=404,l] or similar regex.

i confused if abstract class a{method();method2();} and other class b have inner class c class b{abstract class c{method(){//body}}} and question how extends class c b/c abstract class must extends else unused class. first, let's make simpler - has nothing android directly, , don't need a class @ all. here's want: class outer { abstract class inner { } } class child extends outer.inner { } that doesn't compile, because when create instance of child need provide instance of outer inner constructor: test.java:6: error: enclosing instance contains outer.inner required class child extends outer.inner { ^ 1 error there 2 options can fix this: if don't need refer implicit instance of outer inner , make inner static nested class instead: static abstract class inner { } you change child accept reference instance of outer , , use that call inner constructor, uses surprising syntax, works: child(outer outer) { // cal
