internet explorer - IE truncates frame's src due to ampersand encoding -

never have felt alone, lonelier this guy. found no 1 having same problem.

here's problem i've been stuck weeks now. have page frame in (also happens iframe). frame's src long string multiple url parameters. of these parameters parts of sql query.

now, happens in ie, in combination of these url parameters in frame's src, ampersands (&) encoded &amp ; while length of src string remains if weren't encoded. i.e. following string:

example.html?param1=value1&param2=value2 

will transformed into

example.html?param1=value1&param2=va 

and i'll blank page.

i've examined exact url parameters cause this, there nothing special them. also, in combinations cause problem, while in other don't.

i've examined i'm sending ie, , in not encoded url. i've tried encoding explicitly, still happens.

the problem occurs on ie (10, 11 , edge), not on firefox or chrome.

any appreciated.
