## Symptoms

- * RAD error - Response with wrong status code
* In the RAD error file located at *$FWDIR/log/rad_events/errors/* , the following error appears at the end of the file:   
  `[rad_curl_task.cpp:142] CRadCurlTask::run: [ERROR] Response status = 400`
* In the RAD file *$FWDIR/log/rad_events/errors/* , the resource URL has a space in the request:   
  `Resource=path2.xtracloud.net /xtra3grc.bin`

## Cause

RAD processes a URL request that contains an unexpected space character. This malformed URL results in an HTTP 400 response.  
Due to a software handling condition in the Web Intelligence (WS) module, the request is not dropped as expected.
