percent sign in URI
I realized apache2 web server properyl handles % sign in URIs, i need =
exact functionality on tomcat 5 too.
When I try to pass a parameter containing % sign, the parameter value on =
the server seems null.
like
http://localhost:8080/aSite/aPage?query=hi%everybody
Tomcat 5 cannot handle that, Is there a way to do it with tomcat 5.

What happens if you set URIEncoding="UTF-8" to your connector in
server.xml file?

I'm not sure "properly" is the correct word to use in your
situation. Doing things based on bug is always a big risk. If one day
Apache corrects this bug, your customer will have a great pain in the *ss!

How does your customer system handle this?
http://localhost:8080/aSite/aPage?query=I%fear%dead%results
badly, obviously :)
Possible solutions:
1) You can still try in servlet 'aPage' to grab the request using
request.getQueryString() which should returns you "query=hi%everybody"
2) You can write a servlet filter for /* which will create a new
HttpServletRequest Object with parameters you parse in your way from the
getQueryString() above
3) You can open tomcat source, patch the url decoder, and use it
What ever solution is choosen, customer will be bound to a side effect
of error handling in server.

hi David;
I am aware of the case. As I stated before Apache2 server properly handles
that problem and I need that functionality because our customer's system
built on it.

Hello abdurrahman,
Your url is incorrect, replace it with
http://localhost:8080/aSite/aPage?query=hi%25everybody
According to rfc 1738, 2.2. URL Character Encoding Issues
Octets must be encoded ..., if the use of the corresponding character is
unsafe, ...
The character "%" is unsafe because it is used for encodings of other
characters.
Thus, only alphanumerics, the special characters "$-_.+!*'(),", and
reserved characters used for their reserved purposes may be used unencoded
within a URL.
There is no details in RFC on how to handle badly shaped urls (like % not
followed by 2 hex digits) and thus your urls should not rely upon this.
Regards.

If this were fixed, there would be a host of people complaining about the
opposite. The URL below is inavlid based ont the RFC. getParameter has some
basic assumptions that the url is correctly encoded.
If you wish to place bad data in the query string, I recommend using
request.getQueryString() and parse it yourself.
