Subject Re: handling query strings with ? in
Date Fri, 03 May 2013 13:27:29 GMT
That url *should* be

http://www.example.com/mjs/q.epl?a=b&c=d

Yeah, ? is valid in the query string, but only the first one is special. & 
is supposed to separate field value pairs after the first ? starts them.

If you can't change the code that generates the URL, that is... sad.  I 
wouldn't expect others to support that, but CGI.pm is open source; it 
should be possible to change its code so that it recognizes both & and ? 
as separators - that way if your vendor ever fixes their, um, stuff, your 
code will still work.  Note that you can put your copy of CGI.pm in 
site_perl or your own directory; if that directory is listed in PERL5LIB, 
it will be checked before the core directory.  (Personally, when I compile 
perl, I reorder the includes so site libs are tried first - after all, 
that's where we're most likely to update things first.  Vendors take an 
age to update stuff, and core takes ages.)

handling query strings with ? in



Hi.

We're trying to handle some odd query strings in embperl, eg:

http://www.example.com/mjs/q.epl?a=b?c=d

embperl parses this as:

Using %fdat
Field
Value
a b?c
d


CGI.pm parses this as:

Using CGI.pm
Field
Value
a
b?c=d

I agree that these are some pretty bizarre queries, but annoyingly we 
can't change the source, and embperl seems to handle them pretty badly. 
Googling suggests ? in a query string is probably valid, eg:

http://www.456bereastreet.com/archive/201008/what_characters_are_allowed_unencoded_in_query_strings/

Is there anything that can be done to make embperl behave more as 
expected?
