    1. COThank you so much Brickner !! I was exactly looking for this - processing the tcp payload (but I prefer C for learning). Can you please explain this line of your code : /* start of url - skip "GET " */ url = tcpPayload + 4; Why 4 ? And what should I explore to get more of such values (I read RFC for HTTP, but couldnt understand how to use it). I actually want to read all the HTTP data in that packet. Is it only possible if I reconstruct the full stream ? If yes, can you give me some idea over this reconstruction ? Thanks a lot !!

    2. CO4 is for the "GET " - 3 ASCII characters + space. The RFC includes all of the possible requests names (like GET, POST...). If you only want the HTTP data in the single packet, then no reconstruction is needed. If you want the entire HTTP request, you might need to reconstruct the TCP stream (if the request is more than 1 packet). TCP reconstruction is another (and pretty complicated) issue and you should Google for it or open a different question. By the way, are you using LibPcap or the Windows wrapper WinPcap or is your question more generic?

    3. COI am using libpcap on linux. I was aiming at capturing http packets and extracting some useful information, but reconstruction is undoubtedly too difficult for now. Should I target FTP, which contains just a code and message - is it feasible ? For eg. I would like to extract the username and password from FTP messages.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
