noted that a URL like this is valid syntax:
http://www.mydomain.com/pathseg1;foo=bar/pathseg2;foo=bar2/pathseg3;foo=bar3;foo=bar33?query=value
How the receiving HTTP server interprets the path is unspecified, and I
don't think its mandatory for a HTTP server to support path params at
any
Aye. It just states for that, amongst others, amphersand and semi-colon
are reserved characters within the query string.
This got me looking coz I assumed that the structure of the http get
query string was defined somewhere in rfc rather than just a convention.
I found a few resources
or "http:" from this angle
it seems to leave the part after the ? to denote the start of a query
string vague. Which lead me to a presumption that it was HTTP server
dependant on its interpretation, since for example the CGI.pm modules
changed over from & to ; as the standard par
they
are directly substitutable from various references around the internet.
But your comments imply otherwise.
I'd be happy to lookup "path params" in the same way I do for query
string params with a call:
value = request.getPathParameter(name);
Can I do this ?
Conceptual
In a URL the semi-colon indicates the start of path parameters (as
opposed to the normal query parameters) as defined in rfc2616 (HTTP1.1
spec) et al.
Thus, you can't tell tomcat to use it as a query string delimiter.
JSESSIONID is a well known path parameter for Servlet 2.2+ Containers
I swear I had application code working that was using semi-colons to
delimit query string parameters. I'm sure I've also seen TC append a
";JSESSIONID=" at the end of the URL.
But my own application code written like:
String val = request.getParameters("name&quo
