special characters in urls

[Ph...@mgb.ch]

Hi

I have a question about special characters in urls: 

If I add parameters to urls, I use the 
java.net.URLEncoder.encode to encode the values; 
the javax.servlet.ServletRequest.getParameter-method seems to 
decode such values, but the whole thing seems only to work for the chars

A .. Z
a .. z
0 .. 9 

and a few special ones like blank, -, _ and so. 
Is this right? (this means, I must make sure that no other characters ever
occure in an url ..) 

Thank for any help. 
Philipp

hi philipp,

here is what the API says..for encode() method

The ASCII characters 'a' through 'z', 'A' through 'Z', and '0' through '9'
remain the same.

The space character ' ' is converted into a plus sign '+'.

All other characters are converted into the 3-character string "%xy", where
xy is the two-digit hexadecimal representation of the lower 8-bits of the
character.

and for decode() mthd of URLDecoder class....

1 and 2 remain the same..

The remaining characters are represented by 3-character strings which begin
with the percent sign, "%xy", where xy is the two-digit hexadecimal
representation of the lower 8-bits of the character.


regs,
ravi
