But how to do a POST with an <IMG> tag.
Here is what is happening:
1. user requests ASP page
2. ASP (ie: beyond our control) generates the HTML page which is
downloaded to the browser
3. it places data from a SQL query into the IMG tags which refer to
the servlet with the idea that the servlet can pick up the data and
generate an image as a response. So the tags look like this:
<img src="http://servletcontainer/imageservlet?data....">
4. imageservlet recieves the request but can't handle all the data...
it's too long (the browser is probably truncating it since a servlet
container can handle a query up to 64K long)
You're right more data could be sent with a POST but how does the IMG
tag (or the HTML page generally) generate the POST so that the IMG is
inlined?
Unfortunately you can't do something like this:
<img src="..." method="POST">
The real problem here is the browser - it's absolutely pants that a
browser truncates the GET query. I can see no reason whatsoever for
doing it (even if it is a slightly wierd thing to do it should still
work!).
