Re: refreshing problem

Dear Dietmar,

I must thank you for your patience in hunting out the hidden bugs in
www4mail. I should say that your comments & suggestions have been most
helpful.

Okay on this bug, it is yet another hidden bug. I have made changes to two
subroutines (check_url and break_tag) in order to fix this.

check_url - Added a check for data portions of URLs when extracting the 
		basename, aparently the data part (verything after the ?
		sign) can have the / sign.

break_tag - This routine is used to parse HTML TAG entries
		Well, it could also break a line into parts
		I made the tests stronger, so it split by checking for
		a space or a = sign.
		
Okay, that fixed it..
The new version is up and running on www4mail@wm.ictp.trieste.it and I
will send out a new patch by Monday 05 July 1999.

Thanks
Clement Onime
