RE: CGI Apache Directive: LimitRequestLine

Hi Phil

Alas that isn't possible... there is a constraint in Apache that limits this to 8190... see following help text from Apache:

Maximum request line: allows you to reduce the limit on the allowed size of a client's HTTP request-line below the normal input buffer size compiled with the server. Since the request-line consists of the HTTP method, URI, and protocol version, this option restricts the length of the request-URI. A server needs this value to be large enough to hold any of its resource names, including any information that might be passed in the QUERY_STRING part of a GET request. This option gives the server administrator greater control over abnormal client request behavior, which may be useful for avoiding some forms of denial-of-service attacks. Under normal conditions, the value should not be changed from the default. Valid values include integers between 0 and 8190. The first drop-down menu specifies units of memory. The second drop-down menu provides the options: 

Default: places 8190 in the edit field and "Bytes" in the first drop-down menu. 
Maximum: places 8190 in the edit field and "Bytes" in the first drop-down menu.

This field is optional. Directive: LimitRequestLine

Regards, Andy.

8190 bytes is the default but you increase it by specifying a larger
limit in your httpd.conf. Putting something like:-

LimitRequestLine 32768

should do it if that's all the problem is.

Cheers,
Phil.
