numero = 60401
interpreted = N
texte = I have a little monitor that grabs web pages using TCPCONNECT. I want to grab some info from the headers. Let's say the headers are: HTTP/1.1 200 OK Server: Netscape-Enterprise/6.0 Date: Thu, 09 Dec 2004 15:44:35 GMT Content-length: 8269 Content-type: text/html Last-modified: Thu, 09 Dec 2004 14:56:21 GMT Accept-ranges: bytes Connection: close What I need is the modified date and the content length. I've used the middle context in the past like this: Modified Date= [text show=t][middle startafter=Last-modified: &endbefore=Accept-ranges:][PageContent][/middle][/text] But now we're hitting servers that don't return the headers in the same order that the current servers do. Regardless, I am wanting to use grep for this operation. What I'm looking for is a little help that will find just the value and replace everything except the value with null. Any thoughts on a grep strting?
