I am developing in an AIX server, so I do not know if LWP is installed. Is there any way to check if URL sql text is correct with all these characters used?: ',() (quotes, commas or parenthesis). Because that is why I am using meta http-equiv, with this does not matter if sql text has single quotes, commas or parenthesis. Now I am trying to use JS window.open and another problem arises with these characters.
