java - DWR call throws "Failed to read input" in IE8, appearing too frequent -
this issue occurs in ie8 only, on browser throws http 502 error ,while in apache throws http 103 & application breaks due error
after adding sysout in dwr jar got following logs:

org.directwebremoting.dwrp.parseutil.parsepost(parseutil.java:65) ... 25 more inside marshallexception exiting marshallexception returning plaincallhandler i found few solution above issue :
1)increase keepalivetimout in apache
2)change way of reading input in parseutil class of dwr jar
bufferedreader in = new bufferedreader(new inputstreamreader(req.getinputstream())); to
bufferedreader in = req.getreader(); but issue still reproducible in ie8
i tried give alert message "internal server error. please try again" when exception occur alert not coming. have done changes in dwr-engine.js showing alert message
1)increase keepalivetimout in apache
2)change way of reading input in parseutil class of dwr jar
