Subject [jira] Commented: (HTTPCORE-4) feature request: optional header limits to contain OOME risks
Date Thu, 01 Jun 2006 17:00:32 GMT
    [ http://issues.apache.org/jira/browse/HTTPCORE-4?page=comments#action_12414262 ] 

Ortwin Glück commented on HTTPCORE-4:
-------------------------------------

The line length limitting looks okay. I am still missing a limit for the number of headers.
A malicious server could send an infinite amount of headers and exhaust memory.

> It would be desirable to be able to specify limits in the parsing of HTTP messages, so
that impractically large content (inadvertently or maliciously) fails in a manageable way,
rather than triggering an OutOfMemoryError. 
> One possibility would be to set limits on HTTP header line lengths and number of headers;
once exceeded, an exception would be thrown.  
> Another would be to set a byte-total cap on how much content can be considered to contribute
to the headers; past that cap, an exception would be thrown.
> A possible wrinkle would be implementing compatible limits at other places mid- or late-message
where unbounded numbers of headers could again appear (multipart; chunked; footers).
