Actually, the problem appears to be either in the post buffer or FoxISAPI's handling of the post buffer. Also, the problem is NOT the = sign, but the > sign. I ran a program that tries to send each character to the web server via the post buffer and Foxisapi. The characters that DO NOT work are characters 0-8,11,12,14-31,37,38,60,62. The last 4 of these, % & < >, are the most likely to cause a problem since users can directly type them into memo/character fields. When sending data to the server (Inserts and Updates) I encode these characters on the client side and then decoded them on server side. I don't have to worry about data that is returned from the server - like query results. these characters seem to work fine in XML. That's why I figure the problem is in the post buffer or Foxisapi's handling of the post buffer and therefore the problem only exists when sending post data to the server.
