URL encoding issue

[Harish Sundararaj]

Hi all,

I have a problem with nginx's urlencoding when it does a rewrite and passes
it on to a proxy backend. Below is the config:

location ~ ^/search/([^/]+)/?([^-/&]+)?.*$ {
  set $query $1;
  set $filter $2;

  rewrite ^ /search?q=$query&cat=$filter&$args? last;
}

location ~ ^/(search) {

                proxy_read_timeout 180;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_pass http://load_balance;
}


I match requests like :

/search/queryABC/fitlerDEF
/search/queryABC
/search/queryABC/

and rewrite it to

/search?q=queryABC&cat=filterDEF
/search?q=queryABC
/search?q=queryABC

which all works properly.

Now the problem is if the query has special characters like & , ", ' etc...
they are not urlencoded before rewriting:

Eg:

/search/jhonson&jhonson  becomes  /search?q=jhonson&jhonson    but what I
expect is: /search?q=jhonson&26jhonson

/search/"tourism in paris" becomes /search?q=\"tourism%20in%20paris\"  but
what I expect is /search?q=%22tourism%20in%20paris%22  [This is weird spaces
are urlencoded properly]

Even if i try to urlencode it from the frontend(Javascript) like:

/search/jhonson&26jhonson still becomes /search?q=jhonson&jhonson  which
again looks weird to me !

Am i missing anything? Is there anything that i can do to get what i expect
?

Thanks
Harish
