Thanks, John > > "make a format" is not like a button in wireshirk that has label "make a format" and it will do everything for you. You have to do it yourself. By wireshirk you'll see every type of headers and contents for almost every type of protocols. So you'll use this soft for analyzing the http conversation. Data will not only be in content but also in headers. so parse both if needed. then use the same data and make successive requests. If you are using regular expression it will fail to match if pattern changes. Your pattern '/<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="([^"]*?)" \/>/ will match <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="ABC7D5ACSE" /> but wont match <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="ABC7D5ACSE">. Do you see the difference?? It wont mach <input type="hidden" id="__VIEWSTATE" name="__VIEWSTATE" value="ABC7D5ACSE" /> too. Because the attributes order is changed. Your regex will not work but their website will render very well. to overcome this, you have to use html/xml parser. So you can go to input element. then look for name attribute and if the name attribute is "__VIEWSTATE" then fetch the value attributes content. To make any input element name, value attribute must be present. So your code will match every time. It wont fail in 99.99% case.
