"Try with the full URL instead."
Which one?
http://www.seco-larm.com/RF1ChR.htm is the full URL for the online site, I believe - It's what Explorer 10 is showing in an alert box when I hover over the link in the online pdf. I'm wondering why IE10 is displaying it fine, but not Chrome or FF? The original InDesign url is ../RF1ChR.htm, so the rest was generated by the various browsers.
If I convert to this full URL, then the problem becomes that I'm doing the development off-line with the links going to the folders on my machine, not the final versions online. I don't want the links to point on-line while I'm working on the page. I.e., I couldn't change anything anyway if I were accessing the pdf on line as the sysop here does all the uploading to the actual website, and I wouldn't want to until I'm clear that all the new edits are finished and ready to go.
I.e., there is the site - www.seco-larm.com as the root. Most of the htm goes into that folder. Under that folder are subdirectories for pdfs, images, and pop-ups (small files that pop up in main pages in the root).
Clicking on a model # link takes you to the pdf/page in the pdf subdirectory, and then if you click an image in the pdf, it is supposed to take you somewhere else, at this point back up to the corresponding htm product page in the root directory.
On my machine locally, the absolute url for the link in the pdf to the product page htm however is showing in IE10 as:
"file///E:/FolderName/xxx.htm"
If I were to go into the ID file and change the url to match the online IE10 rendition of the absolute URL, then it wouldn't work locally except to access the file online - if even that... And, if I used the absolute address for the local file, then the browsers working from the online site would presumably be trying to find the E: folder somewhere online.
One would think that the relative addressing - ../RF1ChR.htm - should be sufficient for all the browsers to follow - I mean "move up one level and find this page." How much simpler can it get? IE10 has no problem. I'm baffled as to what to try next. Chrome, BTW, has the same problem locally as on line. It returns a box "This webpage is not available," and the address bar at the top shows ../RF1ChR.htm, but the tab shows "http://../RF1ChR.htm is not" (presumeably 'not working') even though I working locally. Where is it getting that "http://" instead of the "file///E:/FolderName/xxx.htm" that IE10 generates?
