Off-Line Internet
from CD-ROM or Harddisk

A Timesaver Proposal to CytometryNet Sites


1. File Download

- The Martinsried Cytorelay is set up in such a way that only the file names are provided in the: href="" or: img src="" calling statements of .htm files, i.e. the full URL (universal relocator) information consisting of the computer address and the directory tree is appended by the www-server software only at login from outside e.g.:
|a href="offint1.htm"> Off-Line Internet |/a>
is automatically reconstituted to:
|a href=""> Off-Line Internet |/a>.
The | characters are used to avoid interpretation of the above lines as network browser commands. They are replaced by < characters in real .htm files.

- This .htm file setup facilitates mirror site setup and simultaneous Off/On-Line Internet operation because all files can be accessed on harddisk, CD-ROM or On-Line network without modifications.

- Recent Netscape 3.x and Mosaic 2.x browser versions make a distinction between .htm files for UNIX operating systems and .htm files for PC's. The PC as well as the UNIX compatible version of all Martinsried administered .htm text files and .GIF image files can be downloaded in compressed form as: MARTINS1.ZIP and: MARTINS2.ZIP

- Decompression of these files by the PC PKUNZIP program provides the files: MARTPC1.ZIP, MARTUNI1.ZIP and MARTREAD.ME.

- Decompression of the MARTPC1.ZIP and MARTUNI1.ZIP files into separate directories provides the PC and UNIX compatible simultaneous Off/On-Line Internet versions of the Martinsried files.

- To prepare other files for simultaneous Off/On-Line Internet use, a DOS program ( OFFINT1) cuts unwanted local URL and directory informations from .htm or .GIF files. The program furthermore transforms local .html file names into .htm file names for PC users (OFFINTPC.BAT).

2. Local File Setup
2.1 Single Node Download

- In the simplest case the: file is dowloaded by the FTP function of the network browser into a preestablished directory e.g.: C:\INTERNET

- Following unzipping with: PKUNZIP MARTINS1, a bookmark in the appropriate network browser directory has to be generated by the user. Its name is: OFF-LINE Cytorelay Martinsried and its calling sequence: file:///c:/internet/cytorel.htm

- Adressing this bookmark with the network browser will produce the correct image of the Cytorelay homepage. The off-line addressable buttons will be:
- Analytical Cellular Pathology (ACP)
- European Society for Analytical Cellular Pathology (ESACP)
- European Working Group on Clinical Cell Analysis - Deutsche Gesellschaft für Zytometry (DGZ)
- Purdue Mailbox Mirror
- MPI-Biochemie Martinsried
- Consensus/Ring Trials
- Transatlantic www-Mirror
- Internet Operation
All other active buttons are on-line addressed, provided the network connection is active. Otherwise an error message will be generated.

2.2 Multi-Node Download

- The download from multiple nodes into the above file directory may cause improper file addressing due to identical files names from different locations. One way to reduce this danger is to reserve the first three file name characters as file origine e.g. MAR = Martinsried, PUR = Purdue. In this case only five characters are left for file content explanation which may be undesired.

- Alternatively the off-line files of each downloaded node can be localized in a separate directory. A master homepage file is used to address the different homepages. The Martinsried files would be placed accordingly e.g. into the subdirectory: C:\INTERNET\MARTINS.

- The bookmark of the network browser would now address the master homepage MASTER.htm file in the C:\INTERNET directory as:

- The master homepage in turn adresses then e.g. the two homepages of the Martinsried node as:
|a href="martins/cellbio.htm"> Cell Biochemistry, MPI-Biochemie, Martinsried
|a href="martins/cytorel.htm"> Cytorelay Martinsried |/a>

- No modifications are required for any of the downloaded .htm files in the different subdirectories, provided that all off-line file calls contain only the file name without any leading characters like: / or: ./ or: http: in the: href=" or: src=" calling sequences. This is important to avoid the generation of wrong directory trees by the network browser leading to improper off-line file adressing.

3. Computer and Browser Setup
3.1 Off-Line Internet with On-Line Network

Off-line Internet files are best reached by installing bookmark calls with the browser's bookmark option. Under these conditions off-line .htm and image files on hard disk are off-line addressed while on-line localizations continue to be on-line addressed

3.2 Off-Line Internet without Network Card

All network addresses in the .INI file of the network control program have to be preset to: (e.g. in Trumpet TRUMPWSK.INI). The HomePage line in the browser's MOSAIC.INI or NETSCAPE.INI files in the: \WINDOWS directory are set to the location of the off-line MASTER.htm file location on the harddisk e.g:
Upon calling, Mosaic and Netscape browsers immediately display the off-line: MASTER.htm file. All accessible off-line files are callable through the active buttons in the MASTER.htm file. On-line calls generate an error message which is bypassed by a mouse click.

3.3 Off-Line Internet with an Off-Line Network Card

In case a network card without connection to the active network is present in the computer , Mosaic browsers generate a bypassable error message while the operating system gets stuck in our hands with Netscape browsers due to a non bypassable error message.

3.4 Conclusion

Off-line Internet is best setup on either on-line network computers or on off-line network computers without network card.

Off-line Internet, a timesaver !

Download all Martinsried cytometry pages, check the concept, follow the installation instructions (PC) and display text and graphics from your harddisk without network delay
