Hi,
1):
I can't get this small example working:
ab.html:
<html>
<body>
<form action="/ab.yaws"
method="post"
<p> Input data for sun position calculation:<br>
A1 = <input name="a1" type="text" value="3.14159"><br>
A2 = <input name="a2" type="text" value="2.71828"><br>
<input type="submit">
</p>
</form>
</body>
</html>
ab.yaws:
<html>
<body>
<erl>
kv(K,L) ->
{value, {K, V}} = lists:keysearch(K,1,L), V.
out(A) ->
L = yaws_api:parse_post(A),
A1 = kv("a1", L),
A2 = kv("a2", L),
S = A1 + A2,
P = A1*A2,
{html, io_lib:format("A1 + A2 = ~s - A1 x A2 = ~s", [S,P])}.
</erl>
</body>
</html>
I get a "badarith" error. I think Yaws is treating the variables as
strings and not as float but I couldn't solve it.
2):
How to disable the cache of Yaws so I don't have to reload the same page
many times before seeing the changes?
Thank you!

yes. use list_to_float() BIF.
