Calendars Net Premium Server
Address of Your Calendar
You can access your calendar at:
|
Server |
Comment |
plus.calendars.net/NAME [of calendar] |
This goes to new machines and is faster, in part because it does not implement the email notification system. All of the Premium Servers use the same calendar data files. Unless you want your users to be sending out emails via your calendar, this is the best link to put on your web pages. |
prem.calendars.net/NAME [of calendar] |
This server has email notification active. You need to use this server, only if you send out email notifications via the calendar system. |
www.calendars.net/plus/NAME [of calendar] |
This now gets redirected to plus.calendars.net. |
When we move your calendar from the public server to the Premium Server, we also automatically forward to the new location any visitors to the old address (in case some of your users have bookmarked your calendar's address on the public server).
Calendar File Upload and Download
Premium Server users have a separate calendar data file upload/download system, which is reached via the links at the top or bottom of this page.
Moving Graphic Images You Have Uploaded
If you have uploaded graphic images to Calendars Net for use in your calendar on the free server, those files are not automatically available to your calendar on the Premium Server. There are two methods to deal with this:
- The easy way: change the link for each image in your calendar
from <img src=/myimage.gif> to:
<img src=http://www.calendars.net/images/myimage.gif>.
- The other way: use the Premium File Upload system to upload your graphic images to the Premium Server. Please name your image files to link them with your calendar. If your calendar's name is abcd, then please name your graphic files to begin with "abcd" (such as abcdwindow.jpg).
Note: If you upload your images to the Premium Server, then you can use the shorter link, such as:
<img src=/myimage.gif>
Calendar File Backups
At night we make 6 vintages of backups of the Premium Server calendar files. The backup intervals are 1 day, 2 days, 3 days, 4 days, 7 days, and 30 days. So, at all times we will have a backup version of your calendar file that is less than 1 day old, one that is less then 2 days old, one that is less than 3 days old, one that is less than 4 days old, one that is less than 7 days old, and one that is less than 30 days old. So if you make a mistake and somehow overwrite or otherwise mess up your calendar file, you can restore any of these 6 backups of your file. We will tell you how to do that, if you send email to Calendars Net Support: Premium Calendar Restoral from the same email address you used when you ordered your calendar on the Premium Server.
Making Your Calendar Appear to be Located on Your Own Web Site
When someone clicks on a link on your web site to access your calendar on the Calendars Net Premium Server, the web address that appears in the browser's Address bar (Internet Explorer) or Location bar (Netscape) is a Calendars Net URL, such as http://prem.calendars.net/nameofcalendar. Here are two ways you can make the web address stay on your own web site.
Create a Domain Alias
This requires that you know how to use a DNS server to create a domain alias or that you have a webmaster who will do it for you. Go to the primary DNS server for your web address. That is the server that translates your domain name into a numerical IP address. Create a new alias name (also known as a CNAME) for a prefix "cal" (or whatever prefix you might want). For example, if your domain name is mydomainname.com, then you will be creating a new alias name for cal.mydomainname.com.
Set the target host to plus.calendars.net. If you want the email notifications to go out, set it to prem.calendars.net. Then, when anyone who tells the browser to go to cal.mydomainname.com/calendarname will actually go to plus.calendars.net/calendarname or prem.calendars.net/calendarname, but the Address or Location bar in the browser will show cal.mydomainname.com/calendarname. By "calendarname" we mean the name of your calendar.
This is the better of the two methods, because it does not tie your cal.mydomainname.com name to any particular IP address.
Create an "A" Record
This is an entirely different method, inferior to the domain alias method described above. This requires that you know how to use a DNS server to create an "A" record or that you have a webmaster who will do it for you. Go to the primary DNS server for your web address. That is the server that translates your domain name into a numerical IP address. Create a new "A" record for a prefix "cal" (or whatever else you might want). Set the IP address for the prefix "cal" to 207.202.158.85 (for the plus.calendars.net server) or 207.202.158.43 for the prem.calendars.net server.
Let's assume that your web site is www.mywebsite.com. Change the calendar link on your web site to http://cal.mywebsite.com/nameofcalendar. Clicking on that link will bring up your calendar, with a web address on your own site, not on Calendars Net.
This is the worse of the two methods. If Calendars Net ever changes bandwidth providers, we will have to change our IP addresses, which will break your links to your calendar. If the links to your calendar no longer work, then you will need to ping plus.calendars.net or prem.calendars.net in order to obtain the new IP.
Speeding Up Your Calendar by Deleting Old Months of Events
If you continue to add more events to your calendar, its file size will grow. The bigger its file size, the slower it displays. If your calendar is large, you can greatly speed up the loading of your calendar by deleting obsolete old months of events.
This will not be useful, unless your calendar has, say, more than 200 events or has a lot of events that have lengthy pop-up text with them. You can see how large your file is by using the Calendars Net Premium Download System and downloading a copy of your calendar datafile to your own computer. If the file is larger than 100k, you most certainly should reduce its size.
From your calendar, go to Administer this Calendar, Delete Month Events and choose which old months to delete. This function deletes only individual events and does not delete periodic or duration events, no matter when they occur.
One precaution you should take before doing this is to use the se the Calendars Net Premium Download System to download a copy of your calendar datafile to your own computer. If you then accidentally delete more months than you intended, you can use the Calendars Net Premium Upload System to upload the copy of your calendar that you downloaded, thereby returning your calendar to its original state.
Note: If you by accident delete more months than you wanted to, immediately send email to Restore My Calendar and stop editing your calendar. Usually within 24 hours, we will restore the most recent backup of your calendar file. We backup files on all servers every 24 hours.
If you want your users to continue to have access to the old months, while still having a fast current calendar, you can take one of these courses:
- Go to Administer, Publish Calendar, and choose a block of old months to "publish" to static HTML pages.
- Download those pages to your own computer using the instructions at: http://www.calendars.net/calsetup.htm#static.
- Post those static pages on your own web site. As long as all of the static HTML pages are in the same directory, they will correctly interlink
- Use Administer, Delete Months to delete the events from the old months (periodic and duration events are not affected).
Request That We Archive Your Big Calendar. Just send email to Archive a Copy of My Large Premium Calendar, telling us the name of the calendar and the last month you intend to delete. For example, if your calendar is named mycalendar and you intend to delete all events earlier than January 2001, you would state that the last month you intend to delete is December 2000. You then wait to hear back from us, before using the Delete Month Events function. We will make a copy of the calendar and name the copy the same as the original, except with numbers at the end to indicate the last month you intend to delete. In the mycalendar example above, we would name the archive mycalendar0112 (because "0112 means 2001, month 12). After we notify you by return email that the archive has been created, you can proceed to delete old months of events on your original calendar. You and the other users of your calendar can still then reach the archived version (in this example, mycalendar0112), although the archived calendar will probably be much slower to load.
Create and Save a Set of Static Calendar Pages. You can create a set of static HTML pages for the calendar months you want to delete and post those static pages on your own web site, before you use the Delete Month Events function.
This will create on your web site a group of interlinked months. If your calendar pages display graphic images you have previously uploaded to Calendars Net, you will need to put copies of those images, with the same file names, in the directory where you put your static pages. If the images in your calendar pages are links to images elsewhere on the internet, then you do not need to do this.
You can also create the static HTML pages by downloading the free version of iCal, installing it on your own Windows machine. You can then generate the static HTML files, using steps 1 and 3 from the method described above.
What if Old Events are Missing from My Calendar?
If your calendar file becomes so big that it starts to bog down our servers, and if there is no obvious email address on your calendar or on the web page linked to your calendar, then we may be compelled to delete old months of events from your calendar. In general, we will not delete events less than 6 months old, and we will only delete "daily" events, not periodic or duration events. If we do this to your calendar, and you notice that very old events are no longer there, you will find those events in your archived calendar, which is a snapshot of your calendar that we take just before deleting the old events. Your archive calendar is named xxxx1, where xxxx is the name of your calendar. Thus, if your calendar's name is mycalendar, then your archived calendar is named mycalendar1. You can download your archived calendar using the Calendars Net Premium Download System and entering xxxx1.cal as its name (again, where xxxx is the name of your calendar).
In the very unfortunate event that we have to do this to your calendar more than once, then the second archived version will be named xxxx2.cal, where xxxx is the name of your calendar. If we have to do it again, the third archived version will be named xxxx3.cal. The sequence is clear.
The usual reasons that a calendar become huge is that it has many Periodic Events created with the "Generate Daily Events" option. Using this option can instantly create thousands of daily events. Please use it with caution and only when absolutely necessary.
What if Old Events on My Calendar are Gone?
If your calendar has become so huge that our system cannot efficiently load it, we will attempt to contact you and ask you to reduce its size by any of a variety of methods explained at Speeding Up your Calendar by Deleting Old Months of Events. If we cannot find a good way to contact you, we may go ahead and delete some old months of individual events (months that are at least a year old, usually). But before that we will always make a back-up of your huge calendar, with the same name as your calendar with a "1" at the end of it. You can then use the Calendars Net Premium Download System to download that file to your own system for safekeeping, if you want it. Also, your users can use the xxxx1 calendar, if they absolutely need access to very old events.
