Lotus' Dumont answers your iNotes questions

Lotus' Dumont answers your iNotes questions

SearchDomino recently featured a Lotus Live! Series Webcast with Lotus' iNotes product manager Jason Dumont on iNotes Web Access. We asked Jason to answer the questions he was unable to answer during the live event, and we've assembled his answers for you here in the first of a two-part series.

Jason Dumont
Can you re-address what is cached at the client browser? Is any client data ever cached? Is the cache cleared during logoff?
Dumont: Since this is a lengthy answer, I will note that if you are using version 5.0.10 and our ActiveX control, all user data (regardless if it's in the browser cache or system temp directory) can be removed. It's also worth noting that neither browser vendor (Microsoft or Netscape) allow any ISV programmatic access to the browser cache. Client data can be cached on any machine using any product.

If an iNotes Web Access user launches attachments or uses the PDF calendar printing, data will be left in the system temp directory. This is the way Windows works. You may want to recommend that users understand security aspects when accessing data from a shared device and that they use our logout button. In addition, they should use the Internet option in Internet Explorer to delete files in the temporary Internet files directory on browser close.

Besides that, you should note that no document data is cached. We use a caching algorithm that caches design data only (for the most part; see below for exceptions).

  • View data will be in the browser cache if you're using SSL (Secure Sockets Layer). This is because there is a bug on the Microsoft side that causes us to have to store it there if you are using HTTPS. The problem does not occur if you're using HTTP for access, and therefore, no view data is cached. Format is XML.
  • Variable Scripts (different from static scripts in that unique to each person) & GIF files get cached. There's no meaningful data here. At worst, the script file may contain the user name or the file name. The format is JavaScript.
  • If you launch attachments, you will probably have a copy of the attachment in the iNotes Web Access directory off of the system temp directory (not the browser cache). Format is whatever the file was.
  • If you print or preview your calendar using one of the supplied PDF formats, the Adobe Acrobat reader creates a file in the system temp directory that is a copy of the calendar that was just printed. This file remains there until the Adobe Acrobat Reader application is shut down. If you use the plug in the file remains until the acroread32 executable is terminated gracefully. This usually occurs a few seconds after browser shut down. The file is usually named "acr..." followed by a hexadecimal number with a TMP extension. The file will report to be a corrupted PDF file but it opens correctly. Format is PDF.
  • Cookies are never saved to disc and are deleted when the browser is closed. Alarms store is in browser cache in the "X:WinNTProfiles Application DataMicrosoftInternet ExplorerUserData"
    Format is XML.
  • In 5.0.8, if a message body has a IFRAME and then loads another MIME part of the message into the IFRAME, this other MIME part would be retrieved by a separate URL (standard Domino OpenElement URL...not presently overridden by iNotes Web Access in this case). This is probably not setting the cache-control response header to no-cache, and hence, the data would indeed be cached. Any other external parts within the HTML body would also have the same issue (images, etc.).

How much free space is needed for iNotes offline?
Dumont: You need about 100M bytes of free space of the DOLS run time install. After the install process is done, the amount of space you need depends on the size of the mail file plus about 25M bytes for the core DOLS code.

Check out the Redbooks
Jason was unable to answer all of the follow-up questions from his recent Lotus Live! Series Webcast, but many of the answers to those questions can be found in the IBM/Lotus Redbooks. If you don't see a particular question here, check out the iNotes Redbooks.

What are the options for local archiving in iNotes Web Access?
Dumont: This feature will be delivered in an early version of 6.x.

How do you set iNotes to default to plain text for all users?
Dumont: Currently, there is no admin setting to force plain text for all users. This will come in 6.x and is under investigation for 5.0.x.

What browser settings (security) would you recommend for Java and Active X allowances?
Dumont: For the best iNotes Web Access experience, I would recommend you accept our signed ActiveX controls.

Can you give advice on updating unread marks between the iNotes and Notes Clients?
Dumont: It's the same set of calls, and it's the same set of unread marks, so there is no updating necessary. With that said, since it's the same set of calls any unread mark issues you having using just the Notes client would also exist using just iNotes Web Access or both clients.

Can the iNotes client perform lookup across multiple Directories when addressing mail?
Dumont: Yes

We have Notes messaging only licenses (as opposed to full collaboration licenses), so are we permitted to use iNotes Web Access at no charge?
Dumont: Yes, as long as you don't access other Domino applications.

What are the prospects on multiple language support on one server?
Dumont: This is planned for version 6.x. This is currently a limitation of the Domino server.

In iNotes for Domino 6, can the Notes I.D. be required on the local PC?
Dumont: The plan right now is to store it in the mail file.

Initial Setup/ go off-line can be time consuming. I would like to be able to perform initial replicate while attached to my local network, then do future replicates while on dial-up connection?
Dumont: You can do this right now or you can also do a CD-based install of DOLS and the mail file subscription. See the Redbook for details.
